BPS BP2812
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.| Part No. | BP2812 |

DESCRIPTION
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. The operation current is 200uA only, so the auxiliary winding is not needed. It can simplify the system design and reduce the system cost. The BP2812 offers rich protection functions, including LED short circuit protection, current sense resistor short circuit protection and over temperature protection.FEATURES
