BP9736B

BP9736B High Precision Buck-Boost LED Driver Description The BP9736B is a high precision Buck-Boost constant current for LED lighting, it operates in inductor current discontinuous conduction mode under universal input. 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 BP9736B realizes ±5% accuracy of LED current along with excellent line and load regulation. The BP9736B offers rich protection functions including LED open/short circuit protection, thermal regulation, VCC under voltage protection. Features  Available in SOP8 Package  Internal 650V Power MOSFET  Constant current control without secondary sense and feedback circuit.  Integrated HV JFET for VCC Power Supply  No Auxiliary wind...
