BP2833D
Non-isolated Buck Offline LED Driver
Description
The BP2833D 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 BP2833D integrates a 500V power MOSFET.
With patent pending MOSFET driving 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 BP2833D utilizes patent pending current control
method. It can achieve precise output current and
excellent line regulation. The driver operates in
critical conduction mode, the output current does not
change with the inductance and LED output voltage.
The BP2833D offers rich protection functions to
improve the system reliability, including LED open
circuit protection, LED short circuit protection, VCC
under voltage protection, CS resistor short circuit
protection and thermal regulation function.
