π‘ BP2833D Non-Isolated Buck LED Driver IC β Now in Stock
We are pleased to announce the availability of the BP2833D high-precision step-down (buck) constant current LED driver IC from Bright Power Semiconductor (BPSemi). This highly integrated IC is designed for non-isolated LED lighting applications, delivering exceptional performance with minimal external components.
With a built-in 500V power MOSFET, critical conduction mode (CRM) operation, and Β±5% LED current accuracy, the BP2833D is the ideal solution for cost-effective, reliable LED lighting designs.
π‘ What is the BP2833D?
The BP2833D is a high-precision buck (step-down) constant current LED driver IC designed for non-isolated LED lighting applications. It operates in critical conduction mode (CRM) and integrates a 500V power MOSFET, eliminating the need for auxiliary winding detection and supply. This results in a very low external component count, reduced system cost, and compact PCB design.
The IC delivers Β±5% LED output current accuracy across a wide input voltage range (85Vβ265V AC) with excellent line and load regulation.
