Description

The BP3167F is a high precision primary-side

feedback and regulation controller for LED lighting, it

operates in constant current control mode and is

designed to work in inductor current discontinuous

conduction mode and especially suitable for flyback

convertor under universal input.

The BP3167F integrates a 600V power MOSFET, with

patent pending MOSFET driving technique. 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.

The BP3167F offers rich protections to improve the

system reliability, including LED short circuit

protection, thermal regulation function.
