NOT RECOMMENDED FOR NEW DESIGN USE AP1694AS-13 AP1690 SINGLE STAGE PRIMARY SIDE REGULATION PFC CONTROLLER FOR DIMMABLE LED DRIVER Description Pin Assignments The AP1690 is a high performance AC/DC universal input Primary (Top View) Side Regulation Power Factor Controller for dimmable LED driver applications. 1 8 VCC NC The AP1690 provides accurate constant current (CC) regulation while PD 2 7 OUT removing the opto-coupler and secondary control circuitry. It also DIM 3 6 GND eliminates the need of loop compensation circuitry while maintaining stability. The AP1690 achieves excellent regulation and high 5 FB CS 4 efficiency, yet meets the requirement of IEC61000-3-2 harmonic standard. (SO-8) The AP1690 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. In order to regulate the output current of LED current with the phase of Applications dimmer, pin 2 and pin 3 are used to set the peak current of transformer according to the voltage applied to these two pins. Single Stage Power Factor Correction Power Supply for Dimmable LED Lighting The AP1690 is available in SO-8 package. Features Primary Side Control for Output Current Regulation Without Opto-coupler and Secondary CV/CC Control Circuitry Low Start-up Current Good Dimmer Compatibility Tight CC Regulation Performance for Universal Input Mains Voltage Range Eliminates Control Loop Compensation Circuitry Built-in Acceleration Start LED Open Protection LED Short Circuit Protection Over Temperature Protection Over Current Protection Cost Effective for Dimmable LED Driver Solution Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. Green Device (Note 3) Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2.
