BP2812
Constant Current Controller For Non-isolated Buck LED Driver
Description
The BP2812 is a high precision constant current controller, designed for non-isolated buck LED driver. It can operate under universal AC input or 12V~600V DC input. The BP2812 integrates 600V power MOSFET, so it can achieve excellent constant current performance with very few external components
The BP2812 uses high precision current sense circuit and patent method for constant current control, to achieve high precision output current and excellent line regulation. The BP2812 operates in inductor current critical mode. The LED current is constant over wide range of inductance variation and the LED output voltage, so the load regulation is excellent.
The BP2812 uses patent source driver architecture.
