Part Number: BP9833D
Function: Non-isolated Buck Offline LED Driver
Package: DIP 8Pin
Manufacturer: Bright Power Semiconductor ( www.bpsemi.com )
The BP9833D 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 BP9833D 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.
