BP9912B
Non-isolated Buck Constant Current LED Driver
Description
BP9912B is a high precision Buck constant current LED driver.
The device operates in critical conduction mode and is suitable for 85Vac~265Vac universal input offline LED lighting.
The BP9912B integrates a 500V power
MOSFET.
With patent pending
MOSFET driving technique, the operating current of the IC is as low as 180uA.
It doesn’t need the auxiliary winding for VCC supply.
It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized.
BP9912B utilizes patent pending current control method.
It can achieve precise output current and excellent line regulation...
