BP2872 Non-isolated Two Way Buck LED Driver With PWM Dimming Description BP2872 is a non-isolated two buck offline LED driver with PWM dimming. The device operates in critical conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting. BP2872 achieves the dimming function by external PWM controlling the P1 pin and P2 pin. The driver operates in critical conduction mode, the output current does not change with the inductance and LED output voltage. It can achieve precise output current and excellent line regulation. The BP2872 offers rich protection functions to improve the system reliability, including LED open circuit protection, LED short circuit protection, VCC under voltage protection and thermal shutdown function.
