AP1686
AP1686 is Low-Power Off-line PSR LED Controller manufactured by BCD Semiconductor.
Preliminary Datasheet Low-Power Off-line PSR LED Controller General Description
The AP1686 is a high performance AC/DC power supply controller for LED lighting application. The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies. The AP1686 provides accurate constant voltage, constant current (CV/CC) regulation without requiring an opto-coupler and the secondary control circuitry. It also eliminates the need of loop pensation circuitry while maintaining good stability. The AP1686 can achieve excellent regulation and high average efficiency, yet meets no-load consumption less than 30mW. It also has an adjustable built-in...
