BP3166A

BP3166A High Precision PSR Constant Current LED Driver Description The BP3166A 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 BP3166A integrates a 650V 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 BP3166A 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 ...
