NON-ISOLATED DC/DC CONVERTERS 12 Vdc Input 0.9 Vdc - 5.0 Vdc/6 A Output xRPA-06A1A0 RoHS Compliant Rev.B * Non-Isolated * Low Cost * High Efficiency * OCP/SCP * High Power Density * Remote On/Off * Fixed Frequency (200 kHz) * Wide Trim Range * Power Good Output Signal * Under Voltage Lockout (UVLO) * Compact Footprint, Vertical and Horizontal options * Can Sink & Source Current Description The Bel xRPA-06A1A0 is a new high density open frame non-isolated converter series for space sensitive applications. Each model has a wide input range (10.2 Vdc - 13.8 Vdc) and offers a wide output voltage range (0.9 Vdc - 5.0 Vdc) with a 6 A load. An external resistor adjusts the output voltage from its pre-set value of 0.9 Vdc to any value up to the 5.0 Vdc maximum. Typical efficiency is 93% for 5.0 Vdc output at Vin=12 Vdc at full load. Standard features include remote On/Off, over current protection, short current protection, wide input, and programmable output voltage. Part Selection Output Voltage 0.9 V - 5.0 V Input Voltage 10.2 V - 13.8 V Max. Output Current 6A Max.
