BP2866XJ is an external OVP 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 ROVP pin of the chip has an Enable function, which is suitable for switching color matching and induction light applications.

The BP2866XJ chip integrates a 500V power switch, adopts the patented 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 the cost and volume of the peripherals.

The BP2866XJ chip has a built-in high-precision current sampling circuit, and adopts the patented 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.

BP2866XJ has multiple protection functions, including LED short circuit protection, chip power supply under-voltage protection, external OVP, chip temperature overheat regulation, etc.

BP2866XJ is available in SOP7 package.
