Non-isolated buckledConstant current driver chip Overview
BP2863XJ is an external OVP step-down LED constant current driver chip. The chip works in critical continuous mode of inductor current, suitable for 85Vac~265Vac full-range input voltage non-isolated step-down LED constant current power supply. The ROVP pin of the chip has an Enable function, which is suitable for switch color adjustment and sensor light applications.
The BP2863XJ chip integrates a 500V power switch and adopts gate demagnetization detection technology and high-voltage JFET power supply technology. It does not require VCC capacitors and startup resistors, making its peripheral devices simpler and saving peripherals.
cost and volume.
The BP2863XJ chip uses 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 rate. The chip works in the inductor current critical mode formula, the output current does not change with the change of inductance and LED working voltage, and achieves excellent load regulation.
BP2863XJ has multiple protection functions, including LED short circuit protection, chip power supply undervoltage protection, external OVP, chip temperature overheating adjustment, etc.
