The BP2832A 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 BP2832A 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 supplyingthe chip.
It can achieve excellentconstant currentperformance with very few external components so the system cost and size are minimized
The BP2832A 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 BP2832A 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 regulati
