BP3166XH 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 BP3166XH 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.
