BP2822 Datasheet – LED constant current controller – BPS

BP2822 is a precision LED constant current control chip, used in non-isolated Buck LED power supply system for a full range of input AC voltage or DC voltage input of 12V ~ 600V.

BP2822 integrated 600V power MOSFET, requires only a few external components, can achieve excellent constant current characteristic.

BP2822 chip inside with high-precision current sampling circuit, while using the patented constant current control technology, high-precision LED constant current output and excellent line regulation. Chip inductor current in critical mode, the system does not vary with the output current and inductance LED operating voltage changes, achieve excellent load regulation.
