BP2831A Datasheet – Non-isolated Buck Offline LED Driver

Part Number: BP2831A

Function: Non-isolated Buck Offline LED Driver

Package: SOP-8 Pin Type

Manufacturer: BPS ( www.bpsemi.com )





The BP2831A is a high precision buck constant current LED driver. The device operates in critical conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting.

The BP2831A  integrates a 500V power MOSFET. With patent pending MOSFET driving technique, the operating current of the IC is very low . So it doesn’t need the auxiliary winding for supplying the chip. It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized.
