  • Product Description:


    BP2861XJ is an external OVP buck LED constant current driver chip. The chip operates in the critical continuous mode of inductor current and is suitable for non isolated step-down LED constant current power supply with a full range input voltage of 85Vac~265Vac. Chip ROVP pin with Enable function, suitable for

    Used for color switching and induction light applications.

    The BP2861XJ chip integrates a 500V power switch internally, using patented 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 BP2861XJ chip is equipped with a high-precision current sampling circuit and adopts patented constant current control technology to achieve high-precision LED constant current output and excellent line voltage adjustment rate. The chip operates in the critical mode of inductor current, and the output current does not change with the inductance and LED operating voltage, achieving excellent load adjustment rate. BP2861XJ has multiple protection functions, including LED short circuit protection, chip power supply undervoltage protection, external OVP, chip temperature overheating regulation, etc.

    BP2861XJ adopts SOP7 packaging.
