Datasheet Summary
晶丰明源半导体 PWM/Analog Dimmable PSR APFC LED Controller
Description
BP3378A is a high-precision single-stage primary side APFC controller for 90Vac-277Vac universal input application.
BP3378A adopts constant ON-time control to achieve high PF. Inherent THD optimization module can further improve THD. BP3378A operates in BCM mode to improve switching loss, EMI and transformer utilization.
BP3378A supports PWM and analog dimming signal for LED dimming application.
BP3378A is packaged in SOP-8.
