BP2336JC Non-isolated Buck APFC LED Driver Description Features The BP2336JC is a high precision non-isolated buck  Fast start up and power supply with HV JFET driver with active PFC, specially designed for high  Integrated with 500V Power MOSFET mains input offline constant current LED lighting. The  Active PFC for High Power Factor and Low THD driver with on-chip PFC circuit achieves high power  ±3% LED Output Current Accuracy factor and low THD. Operating in critical conduction  Excellent Line and Load Regulation mode, the power MOSFET switching loss is reduced  Critical Conduction Mode Operation and the inductor is fully utilized.  Ultra Low (400uA) Operating Current  LED Short Protection The BP2336JC integrates a 500V power MOSFET.  LED Open Protection (OVP) With few external components, the LED output  Current Sensing Resistor Open Protection current can be precisely controlled.  Cycle by Cycle Current Limit The BP2336JC utilizes patented floating ground  VCC Under Voltage Protection structure. The inductor current is sensed during the  Auto Fault Recovery whole switching cycle. So it achieves high precision  Thermal Regulation Function output current control, and excellent line regulation and
