1 / 8 page  BP9916B Non-isolated Buck Offline LED Driver BP9916B_EN _DS_Rev.1.0 www.bpsemi.com 1 BPS Confidential – Customer Use Only 晶丰明源半导体 Description BP9916B 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 BP9916B 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. BP9916B utilizes patent pending current control method. It can achieve precise output current and excellent line regulation. The driver operates in critical conduction mode, the output current does not change with the inductance and output voltage. The BP9916B offers rich protections to improve the system reliability, including LED short circuit protection, VCC under voltage protection and thermal regulation function. Typical Application Features Internal 500V Power MOSFET Integrated HV JFET for VCC Power Supply Critical Conduction Mode Operation Low Operating Current ±5% LED Output Current Accuracy LED Short Protection VCC Under Voltage Protection Thermal Regulation Function Available in SOP8 Package Applications LED Candle Light LED Bulb Other LED Lighting AC DRAIN CS NC CS NC 1 2 3 4 8 7 6 5 BP9916B CS VCC CS Figure 1.
