BP3167DH/EH/FH Low PF Isolation Constant Current Driver Chip 24W Simplified Solution

BP3167XH is a high-precision flyback LED constant current driver chip. The chip operates in inductor current intermittent mode and is suitable for isolated flyback LED constant current power supply with a full range of input voltages from 85Vac to 265Vac. The BP3167XH chip integrates a high-voltage power switch internally, using gate demagnetization detection technology and high-voltage JFET power supply technology. It does not require VCC capacitors and starting resistors, making its peripheral devices simpler and saving peripheral costs and volume. 

Advantages: No VCC capacitor, no starting resistor, integrated high-voltage power supply function, no need for auxiliary winding detection and power supply. Wide range input voltage ± 5%, LED output current accuracy, LED short circuit protection, LED open circuit protection, EN function chip power supply, undervoltage protection, overheating regulation function 

Application areas: LED bulb light, LED tube light, other LED lighting
