晶丰明源半导体 Non-isolated Buck Constant Current LED Driver
Description
BP9912C 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 BP9912C 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 ponents, so the system cost and size are minimized.
BP9912C utilizes patent pending current control method. It can achieve precise output current and excellent line...
