3 Program Features:

?BP2861AJL 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. ?BP286IAJL chip integrates 500V power switch, adopts gate demagnetization detection technology and high-voltage JFET power supply technology, without VCC capacitor and start-up resistor, making its peripheral devices simpler and saving peripheral cost and volume.

The BP2861AJL chip has 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.

BP2861AL has multiple protection functions, including LED short-circuit protection, chip power supply under-voltage protection, external OVP, chip temperature overheat regulation, etc. BP2861AJL is available in SOP7 package. ?
