BP9833D
Non-isolated Buck Offline LED Driver
Description
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.
The BP9833D utilizes patent pending current control method. It can achieve precise output current and excellent line regulation.
