BP3166XS 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 BP3166XS chip integrates a high-voltage power switch internally, using gate demagnetization detection technology and high-voltage JPET 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, multi lamp parallel connection without flicker, chip power supply, undervoltage protection, overheating regulation function 

Application Fields: Bubble Light, LED, Simple Light, Other LED Lighting
