General Description

The AP1682 is a high performance AC/DC universal

input Primary Side Regulation Power Factor

Controller for LED driver applications. The device

uses Pulse Frequency Modulation (PFM) technology

to regulate output current while achieving high power

factor and low THD.

The AP1682 provides accurate constant current (CC)

regulation while removing the opto-coupler and

secondary control circuitry. It also eliminates the

need of loop compensation circuitry while

maintaining stability. The AP1682 achieves excellent

regulation and high efficiency, yet meets the

requirement of IEC61000-3-2 harmonic standard.

The AP1682 features low start-up current, low

operation current and high efficiency. It also has rich

protection features including over voltage, short

circuit, over cu rrent, over temperat ure p rot ection etc.

The AP1682 is available in SOIC-8 package.
