BP9112A

BP9112A High Precision PSR Constant Current LED Driver Description The BP9112A 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 recommended to less than 3W. The device integrates a 650V power MOSFET. With very few external components, the converter achieves excellent constant current control. And it does not need auxiliary winding for powering the IC or voltage sensing, hence the system size and cost is greatly reduced. Since using the proprietary high accurate current sense method, the BP9112A realizes ±6% accuracy of LED current along with excellent line and load regulation. The BP9112A offers rich protection functions including LED open/short circuit protection, thermal regulation, VCC under voltage protection. Features  Avail...
