BP9911A Non-isolated Buck Offline LED Driver Description BP9911A 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 BP9911A integrates a 500V power MOSFET. With patent pending MOSFET driving technique, the operating current of the IC is as low as 180uA. It doesn’t need the auxiliary winding for VCC supply. It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized. BP9911A utilizes patent pending current control method. It can achieve precise output current and excellent line regulation.
