AP1682MTR-OG1

NOT RECOMMENDED FOR NEW DESIGN - USE AP1682EMTR-G1 AP1682 SINGLE STAGE PRIMARY SIDE REGULATION PFC CONTROLLER FOR LED DRIVER Description Pin Assignments 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. (Top View) 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. 1 8 VCC VS 2 7 OUT VPK 3 6 GND CS 4 5 FB SOIC-8 Applications  The AP1682 is available in SOIC-8 package.
