SINGLE STAGE PRIMARY SIDE REGULATION PFC CONTROLLER FOR LED DRIVER
The AP1682E 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
The AP1682E 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 AP1682E achieves excellent regulation and
high efficiency, yet meets the requirement of IEC61000-3-2 harmonic
The AP1682E features low start-up current, low operation current and
high efficiency. It also has rich protection features including over
voltage, short circuit, over current protection etc.
