Overview
Data Sheet Single Stage Primary Side Regulation PFC Controller For LED Driver AP1682 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 current, over temperature protection etc.
The AP1682 is available in SOIC-8 package.
Features • Primary Side Control for Output Current Regulation Without Opto-coupler and Secondary CV/CC Control Circuitry Low Start-up Current High Power Factor and Low THD for Universal Input Range Tight CC Regulation Performance for Universal Input Mains Voltage Range Eliminates Control Loop Compensation Circuitry Built-in Acceleration Start Open-load and Reload Detection Over Voltage and Short Circuit Protection Over Temperature Protection Over Current Protection Cost Effective Total PFC LED Driver Solution • • • • • • • • • • Applications • Single Stage Power Factor Correction Power Supply for LED Lighting SOIC-8 Figure 1.
