BP2371XG
BP2371XG is Non-isolated APFC Buck LED Driver manufactured by BPS.
Non-isolated APFC Buck LED Driver
Description
BP2371XG is a high precision non-isolated APFC buck LED driver, specially designed for universal mains with constant current control. BP2371XG operates in Critical Conduction Mode to reduce the switching loss and optimize the EMI.
BP2371XG remove the VCC capacitor, P capacitor and RCS resistor to simplify the external BOM. And it utilizes specific current detection, with few external ponents, it achieves high precision output current, excellent line regulation and load regulation.
BP2371XG offers full of protection functions to improve the system reliability, including LED load short protection. The system reliability is further improved by the thermal and input overvoltage regulation function . The output current is reduced when the driver is in condition of over temperature or input overvoltage.
