BP2306XJ

Dimmable Non-isolated APFC Buck LED Driver

Description Features
BP2306XJ is a PWM/Analog dimmable high precision ◼ Compatible with PWM and Analog Dimming
non-isolated buck APFC LED driver, specially designed ◼ PWM Dimming Range 1~100%
for universal mains with constant current control. ◼ Analog Dimming Range 5~100%
◼ Active-PFC for High PF and Low THD
Suitable for 90Vac-265Vac full range input voltage.
◼ Ultra low standby power consumption
BP2306XJ adopts high voltage start up circuit，internals ◼ Single winding inductance
the COMP capacitor to simplify the external BOM. And ◼ No COMP capacitor
it utilizes patented current detection, with few external ◼ ±3% LED Output Current Accuracy
components, it achieves high precision output current,
◼ Excellent Line and Load Regulation
◼ VCC Under Voltage Protection
excellent line regulation and load regulation.
◼ Cycle by Cycle Current Limit
BP2306XJ offers various protection functions, including ◼ LED Short Protection
LED load short protection, VCC under voltage protection, ◼ Thermal Regulation Function
and over temperature protection, which enhance system ◼ SOP-8 Package
reliability.
Applications
◼ LED smart Bulbs
◼ Other smart LED Lighting
