BP2861-SJ/AJ/BJ/CJ/DJ

BP2861XJ is an external OVP step-down LED constant current driver chip that operates in inductor current critical continuous mode and is suitable for non isolated step-down LED constant current power supply with a full range of input voltages from 85Vac to 265Vac. The ROVP pin of the chip has an Enable function, which is suitable for switch color adjustment and sensor light applications. The BP2861XJ chip integrates a five hundredV power switch internally, using gate 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.

Compatible with BP2866XJ pin, integrated with 600V ultra fast recovery diode, no VCC capacitor, no starting resistor, integrated with high voltage power supply function, external moisture-proof OVP function, no flashing under low bus voltage, multiple parallel lights without flashing, Enable function, compatible with switch color matching and induction lights, 5% LED output current accuracy, LED short circuit protection, overheating adjustment function, packaged in SOP7

Application areas: LED candle lights, LED bulb lights, other LED lighting
