BP3177DF Isolated Low PF Dimmable LED Driver Description The BP3177DF is an isolated low PF dimmable LED driver controller, compatible 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 excellent line and load regulation. Primary-side regulation also helps to eliminate second-side components and reduce system cost. The BP317DF provides with multiple protections to assure reliability of LED driver design. The BP3177DF is available in DIP-7 package.
