BP2373CR is a high-precision non isolated buck PFC LED driver chip with source power factor correction, designed specifically for general-purpose power supplies and featuring constant current control. And BP2373CR operates in critical conduction mode, reducing switch losses and optimizing EMI. BP2373CR integrates rectifier bridge freewheeling diode and VCCCOMP capacitor to simplify external circuits. It adopts unique current detection technology, reducing external components while achieving high-precision output current, and has good linear and load adjustment rates.
Advantages: Active power factor correction, 0.7PF without VCC and COMP capacitors, integrated 600V ultra fast recovery diode, integrated 800V rectifier bridge, external current sampling resistor, inductor, current critical continuous mode, LED short circuit protection, cycle by cycle current limiting, overheating regulation function, packaged in ASOP7
Application areas: LED bulb light, LED tube, other LED lighting
