描述 Description

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 THD.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. TheAP1682E achieves excellent regulation and high efficiency, yet meets the requirement of IEC61000-3-2 harmonic standard.The AP1682E features low start-up current, low operation current and high efficiency. It also has rich protection.
