A Product Line of Diodes Incorporated AP1690 Description Features The AP1690 is a high performance AC/DC universal input Primary Side Regulation Power Factor Controller for dimmable LED driver applications. The AP1690 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 AP1690 achieves excellent regulation and high efficiency, yet meets the requirement of IEC61000-3-2 harmonic standard. 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 dimmer, pin 2 and pin 3 are used to set the peak current of transformer according to the voltage applied to these two pins. Primary Side Control for Output Current Regulation Without Optocoupler 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) The AP1690 is available in SO-8 package.
