Overview
BP3126S High Precision PSR Constant Current LED Driver Description The BP3126S is a high precision primary-side feedback and regulation controller for LED lighting, it operates in constant current control mode and is designed to work in inductor current discontinuous conduction mode and extremely suitable for flyback convertor under universal input, the output power of system should be less than 24W.
The BP3126S integrates 650V power MOSFET.
Since adopting primary sense and feedback control technology, the secondary sense and feedback circuit is eliminated.
The loop compensation components are also removed while maintaining stability overall operating conditions.
The low component counts and low BOM cost are realized.
Since using the proprietary high accurate current sense method, the BP3126S realizes ±3% accuracy of LED current along with excellent line regulation and load regulation.
The BP3126S offers rich protection functions including LED short circuit protection, LED open circu...
