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.

A Buck Offline LED Driver is an electronic circuit or device designed to efficiently power and control LEDs (Light Emitting Diodes) from an AC (Alternating Current) input voltage source. This type of LED driver is used to convert higher AC voltages (e.g., mains voltage) to a lower and regulated DC (Direct Current) voltage suitable for driving LEDs. “Buck” refers to a specific type of DC-DC converter topology used for this purpose.
