The BP2836Dis a high precision buckconstant current LEDdriver. The device operates in critical conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting. The BP2836Dintegrates a 500V power MOSFET. With patent pending MOSFET driving technique, the operating current of the IC is very low.So it doesn’t need the auxiliary winding for supplyingthe chip. It can achieve excellentconstant currentperformance with very few external components, sothe system cost and size are minimized. The BP2836Dutilizes 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 LED outputvoltage.The BP2836Doffers rich protection functions to improve the system reliability, including LED open circuit protection, LED short circuit protection, VCC under voltage protection, CS resistor shortcircuit protection and thermal regulation function.
