Datasheet Summary
High Precision PSR Constant Current LED Driver
Description
The BP3123 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 especially suitable for flyback convertor under universal input. The output power of system is remended to less than 5W.
The BP3123 integrates 650V power MOSFET. Since adopting primary sense and feedback control technology, the secondary sense and feedback circuit is eliminated. The loop pensation ponents are also removed while maintaining stability overall operating conditions. It uses patent...
