BP3177DF Description
The BP3177DF is an isolated low PF dimmable LED driver controller, patible with PWM or analog dimming signal for Constant Current Reduction (CCR) dimming, to provide high-precision and flicker-less light output. The BP317DF works in BCM and QR mode to improve system efficiency and EMI, and to reduce the size of Flyback transformer. The BP3177DF adopts advanced primary-side constant current algorithm to provide with...
