💡 BP2831AJ Non-Isolated Buck LED Driver IC – Now in Stock
We are pleased to announce the availability of the BP2831AJ 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 ±5% LED current accuracy, the BP2831AJ is the ideal solution for cost-effective, reliable LED lighting designs.
💡 What is the BP2831AJ?
The BP2831AJ is a high-precision buck (step-down) constant current LED driver IC designed for non-isolated LED lighting applications. It operates in indicator current 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 ±5% LED output current accuracy across a wide input voltage range (85V–265V AC) with excellent line and load regulation.
