R1224N SERIES PWM/VFM step-down DC/DC Controller NO.EA-096-160524 OUTLINE The R1224N Series are CMOS-based PWM step-down DC/DC Converter controllers with low supply current. Each of these ICs consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, a phase compensation circuit, a soft-start circuit, a protection circuit, a PWM/VFM alternative circuit, a chip enable circuit, resistors for output voltage detect, and input voltage detect circuit. A low ripple, high efficiency step-down DC/DC converter can be easily composed of this IC with only several external components, or a power-transistor, an inductor, a diode and capacitors. Output Voltage is fixed or can be adjusted with external resistors (Adjustable types are without PWM/VFM alternative circuit). With a PWM/VFM alternative circuit, when the load current is small, the operation is automatically switching into the VFM oscillator from PWM oscillator. Therefore, the efficiency at small load current is improved. Several types of the R1224Nxxx, which are without a PWM/VFM alternative circuit, are also available. If the term of maximum duty cycle keeps on a certain time, the embedded protection circuit works. The protection circuit is Reset-type protection circuit, and it works to restart the operation with soft-start and repeat this operation until maximum duty cycle condition is released. When the cause of large load current or something else is removed, the operation is automatically released and returns to normal operation. Further, built-in UVLO function works when the input voltage is equal or less than UVLO threshold, it makes this IC be standby and suppresses the consumption current and avoid an unstable operation.

When you control the CE pin by another power supply, do not make its "H" level more than the voltage level of VIN pin. Set external components as close as possible to the IC and minimize the connection between the components and the IC. In particular, a capacitor should be connected to VIN pin with the minimum connection. Make sufficient ground and reinforce supplying. A large switching current could flow through the connection of power supply, an inductor and the connection of VIN. If the impedance of the connection of power supply is high, the voltage level of power supply of the IC fluctuates with the switching current. This may cause unstable operation of the IC. Protection circuit may work if the maximum duty cycle continue for the time defined in the electrical characteristics. Once after stopping the output voltage, output will restart with soft-start operation. If the difference between input voltage and output voltage is small, the protection circuit may work. Use capacitors with a capacity of 22F or more for VOUT pin, and with good high frequency characteristics such as tantalum capacitors. We recommend you to use output capacitors with an allowable voltage at least twice as much as setting output voltage. This is because there may be a case where a spike-shaped high voltage is generated by an inductor when an external transistor is on and off. Choose an inductor that has sufficiently small D.C. resistance and large allowable current and is hard to reach magnetic saturation. And if the value of inductance of an inductor is extremely small, the ILX may exceed the absolute maximum rating at the maximum loading. Use an inductor with appropriate inductance. Use a diode of a Schottky type with high switching speed, and also pay attention to its current capacity. Do not use this IC under the condition with VIN voltage at equal or less than minimum operating voltage. When the threshold level of an external power MOSFET is rather low and the drive-ability of voltage supplier is small, if the output pin is short circuit, input voltage may be equal or less than UVLO detector threshold. In this case, the devise is reset with UVLO function that is different from the reset-protection function caused by maximum duty cycle. With the PWM/VFM alternative circuit, when the on duty cycle of switching is 35% or less, the R1224N alters from PWM mode to VFM mode (Pulse skip mode). The purpose of this circuit is raising the efficiency with a light load by skipping the frequency and suppressing the consumption current. However, the ratio of output voltage against input voltage is 35% or less, (ex. VIN>8.6V and VOUT=3.0V) even if the large current may be loaded, the IC keeps its VFM mode. As a result, frequency might be decreased, and oscillation waveform might be unstable. These phenomena are the typical characteristics of the IC with PWM/VFM alternative circuit. If the input voltage is equal or more than 6V, R1 and C2 in the typical application are necessary as a VIN filter to prevent unstable operation. The performance of power source circuits using these ICs extremely depends upon the peripheral circuits. Pay attention in the selection of the peripheral circuits. In particular, design the peripheral circuits in a way that the values such as voltage, current, and power of each component, PCB patterns and the IC do not exceed their respected rated values. 8 R1224N How to Adjust Output Voltage and about Phase Compensation As for Adjustable Output type, feedback pin (VFB) voltage is controlled to maintain 1.0V. Output Voltage, VOUT is as following equation: VOUT: R2R4VFB: R2 VOUTVFB(R2R4)/R2 Thus, with changing the value of R2 and R4, output voltage can be set in the specified range. In the DC/DC converter, with the load current and external components such as L and C, phase might be behind 180 degree. In this case, the phase margin of the system will be less and stability will be worse. To prevent this, phase margin should be secured with proceeding the phase. A pole is formed with external components L and C3. Fpole ~ 1/2 L C3 A zero (signal back to zero) is formed with R4 and C4. Fzero~1/(2R4C4) For example, if L27H, C347F, the cut off frequency of the pole is approximately 4.5kHz. To make the cut off frequency of the pole as much as 4.5kHz, set R433k and C41000pF. If VOUT is set at 2.5V, R222k is appropriate. R3 prevents feedback of the noise to VFB pin, about 2.7k is appropriate value.

The operation will be explained with reference to the following diagrams: <Basic Circuits> <Current through L> i1 IL ILmax IOUT VIN Lx Tr SD VOUT L ILmin topen i2 CL GND ton toff T1/fosc Step 1: Lx Tr. turns on and current IL (=i1) flows, and energy is charged into CL. At this moment, IL increases from ILmin. (=0) to reach ILmax. in proportion to the on-time period (ton) of Lx Tr. Step 2: When Lx Tr. turns off, Schottky diode (SD) turns on in order that L maintains IL at ILmax, and current IL (=i2) flows. Step 3: IL decreases gradually and reaches ILmin. after a time period of topen, and SD turns off, provided that in the continuous mode, next cycle starts before IL becomes to 0 because toff time is not enough. In this case, IL value is from this ILmin (>0). In the case of PWM control system, the output voltage is maintained by controlling the on-time period (ton), with the oscillator frequency (fosc) being maintained constant. Discontinuous Conduction Mode and Continuous Conduction Mode The maximum value (ILmax) and the minimum value (ILmin) current which flow through the inductor is the same as those when Lx Tr. is ON and when it is OFF. The difference between ILmax and ILmin, which is represented by I; IILmax-ILminVOUTtopen/L(VIN-VOUT)ton/L ................................... Equation 1 wherein, T1/foscton+toff duty (%)ton/T100tonfosc100 topen toff In Equation 1, VOUTtopen/L and (VIN-VOUT)ton/L are respectively shown the change of the current at ON, and the change of the current at OFF. When the output current (IOUT) is relatively small, topen<toff as illustrated in the above diagram. In this case, the energy is charged in the inductor during the time period of ton and is discharged in its entirely during the time period of toff, therefore ILmin becomes to zero (ILmin=0). When Iout is gradually increased, eventually, topen becomes to toff (topen=toff), and when IOUT is further increased, ILmin becomes larger than zero (ILmin>0). The former mode is referred to as the discontinuous mode and the latter mode is referred to as continuous mode. 10 R1224N In the continuous mode, when Equation 1 is solved for ton and assumed that the solution is tonc, toncTVOUT/VIN ..................................................................................... Equation 2 When ton<tonc, the mode is the discontinuous mode, and when tontonc, the mode is the continuous mode. OUTPUT CURRENT AND SELECTION OF EXTERNAL COMPONENTS When Lx Tr. is ON: (Wherein, Ripple Current P-P value is described as IRP, ON resistance of Lx Tr. is described as Rp the direct current of the inductor is described as RL.)

Equation 7 Consider ILmax, condition of input and output and select external components. The above explanation is directed to the calculation in an ideal case in continuous mode. 11 R1224N External Components 1. Inductor Select an inductor that peak current does not exceed ILmax. If larger current than allowable current flows, magnetic saturation occurs and make transform efficiency worse. When the load current is definite, the smaller value of L, the larger the ripple current. Provided that the allowable current is large in that case and DC current is small, therefore, for large output current, efficiency is better than using an inductor with a large value of L and vice versa. 2. Diode Use a diode with low VF (Schottky type is recommended.) and high switching speed. Reverse voltage rating should be more than VIN and current rating should be equal or more than ILmax. 3. Capacitors As for CIN, use a capacitor with low ESR (Equivalent Series Resistance) and a capacity of at least 10F for stable operation. COUT can reduce ripple of Output Voltage, therefore 47F or more value of tantalum type capacitor is recommended. 4. Lx Transistor Pch Power MOSFET is required for this IC. Its breakdown voltage between gate and source should be a few V higher than Input Voltage. In the case of Input Voltage is low, to turn on MOSFET completely, to use a MOSFET with low threshold voltage is effective. If a large load current is necessary for your application and important, choose a MOSFET with low ON resistance for good efficiency. If a small load current is mainly necessary for your application, choose a MOSFET with low gate capacity for good efficiency. Maximum continuous drain current of MOSFET should be larger than peak current, ILmax. 12 R1224N TIMING CHART VOUT Set Output Voltage VIN UVLO Voltage Input Voltage Rising Time UVLO Reset VOUT Set Output Voltage CE Protection Circuit Delay Time VOUT Set Output Voltage EXT Reset Protection VOUT VOUT Set Output Voltage Stable Operation Soft Start Stable Operation Soft Start Soft Start Stable Operation Soft Start The timing chart shown above describes the changing process of input voltage rising, stable operating, operating with large current, stable operating, input voltage falling, input voltage recovering, and stable operating. First, until when the input voltage (VIN) reaches UVLO voltage, the circuit inside keeps the condition of pre-standby. Second, after VIN becomes beyond the UVLO threshold, soft-start operation starts, when the soft-start operation finishes, the operation becomes stable. If too large current flows through the circuit because of short or other reasons, EXT signal ignores that during the delay time of protection circuit. (The current value depends on the circuit.) After the delay time passes, reset protection works, or EXT signal will be "H", then output will turn off, then soft-start operation starts. After the soft-start operation, EXT signal will be "L", but if the large current is still flowing, after the delay time of protection circuit passes, reset protection circuit will work again, the operation will be continuously repeated unless the cause of large current flowing is not removed. Once the cause of the large current flowing is removed, within the delay time, the operation will be back to the stable one. If the timing for release the large current is in the protection process, the operation will be back to the normal one after the soft-start operation. If the VIN becomes lower than the set VOUT, that situation is same as large current condition, so protection circuit may be ready to work, therefore, after the delay time of protection circuit, EXT will be "H". Further, if the VIN is lower than UVLO voltage, the circuit inside will be stopped by UVLO function. After that, if VIN rises, until when the VIN reaches UVLO voltage, the circuit inside keeps the condition of spre-standby. Then after VIN becomes beyond the UVLO threshold, soft-start operation starts, when the soft-start operation finishes, the operation becomes stable. 13 R1224N TEST CIRCUITS Output Voltage, Oscillator
