BP2832A PDF Datasheet – Buck Offline LED Driver

Posted on by pinout

Part Number: BP2832A

Function: Non-isolated Buck Offline LED Driver

Package: SOP-8 Pin Type

Manufacturer: BPS ( Bright Power Semiconductor )

Images:BP2832A datasheet

Description

The BP2832A 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 BP2832A 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.
