BP2863KK is a step-down LED constant current driver chip. The chip operates in inductor current critical continuous mode and is suitable for non isolated step-down LED constant current power supply with a full range of input voltages from 85Vac to 265Vac. The BP2863KK chip integrates a five hundredV power switch internally, using gate demagnetization detection technology and high-voltage JFET power supply technology, without the need for VCC capacitors and starting resistors, making its peripheral devices simpler and saving peripheral costs and volume.

The BP2863KK chip adopts a built-in high-precision current sampling circuit and constant current control technology to achieve high-precision LED constant current output and excellent line voltage adjustment rate. The chip operates in inductor current critical mode, and the output current does not vary with changes in inductance and LED operating voltage, achieving excellent load regulation. BP2863KK has multiple protection functions, including LED short circuit protection, chip power supply undervoltage protection, chip temperature overheating regulation, etc. BP2863KK is packaged in ASOP7.
