1 / 2 page  BP3167F High Precision PSR Constant Current LED Driver BP3167F_CN_DS_Rev.1.0 www.bpsemi.com 1 Bright Power Semiconductor Co. Confidential – Customer Use Only Description The BP3167F is a high precision primary-side feedback and regulation controller for LED lighting, it operates in constant current control mode and is designed to work in inductor current discontinuous conduction mode and especially suitable for flyback convertor under universal input. The BP3167F integrates a 600V power MOSFET, with patent pending MOSFET driving technique. 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. The BP3167F offers rich protections to improve the system reliability, including LED short circuit protection, thermal regulation function. Features No VCC capacitor and no starting resistance Integrated HV JFET for Power Supply No Auxiliary winding for sensing and supplying Universal input voltage ±5% LED Output Current Accuracy LED Short Protection LED Open Protection Thermal regulation function Package：DIP7 Applications LED Bulb LED Candle Light Other LED Lighting Typical Application NP NS AC DRAIN CS NC 7 5 1 2 3 4 HV GND DRAIN ROVP 6 Option BP3167F Figure 1.
