Part Number : BP3125
Function : High Precision PSR Constant Current LED Driver
Package : DIP 8 Pin
Manufacturers : Bright Power Semiconductor
The IC 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 12W.
The Device integrates 600V 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.
1. Built-in 600V Power MOSFET
2. Constant current control without secondary sense and feedback circuit.
3. Universal input voltage
4. LED short and open circuit protection
5. VCC under-voltage protection
