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.
