I. Main overview

BP2863XK is a step-down LED constant current driver chip. The chip works in the critical continuous mode of inductor current and is suitable for non-isolated step-down LED constant current power supply with full range input voltage of 85Vac~265Vac.

The BP2863XK chip integrates a 500V power switch, adopts gate demagnetization detection technology and high-voltage JFET power supply technology, and does not require VCC capacitors and start-up resistors, making its peripheral devices simpler and saving peripheral costs and volume.

The BP2863XK chip adopts built-in high-precision current sampling circuit and constant current control technology to achieve high-precision LED constant current output and excellent line voltage regulation. The chip works in the critical mode of inductor current, and the output current does not change with the change of inductance and LED operating voltage, achieving excellent load regulation.

BP2863XK has multiple protection functions, including LED short circuit protection, chip temperature overheat regulation, etc.

BP2863XK is available in ASOP7 package.
