BP2838G

BP2838G PWM Dimming Non-isolated Buck Offline LED Driver Description The BP2838G support a PWM dimming 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 BP2838G integrates 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 supplying the chip. It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized. The BP2838G 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 BP2838G offers rich protection functions to improve the system reliability, including LED open circuit protect...
