BCD AP1682M-G1 Single stage primary side regulation pfc controller for led driver Datasheet

Data Sheet
Single Stage Primary Side Regulation PFC Controller For LED Driver
General Description
Features
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.
