Overview
BP2857D Non-isolated Buck Offline LED Driver Description The BP2857D 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 BP2857D integrates a 500V power MOSFET.
With patent pending floating ground structure and current sensing technique, the operating current of the IC is very low.
So it doesn’t need the auxiliary winding for supplying the chip.
It can achieve excellent constant current performance with very few external components, so the system cost and size are minimized.
The BP2857D utilizes patent pending current control method.
It can achieve precise output cu...
