BP2838

BP2838 PWM dimmable Non-isolated Buck LED Driver Description The BP2838 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 BP2838 integrates a 500V power MOSFET. With patent pending MOSFET driving technique, the operating current of the IC is very low. It doesn’t need the auxiliary winding for supplying the chip. It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized. The BP2838 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 LED output voltage. The BP2838 offers rich protection functions to improve the system reliability, LED short circuit protection, VCC under voltage protection, CS res...
