The showing circuit provides a drive power white LED solutions, that is,white LED is driven by working in the buck model of standard boost converter.This solution efficiency is as high as 96%, compared with standard solution efficiency with only 85%, it has a lot of practical advantages. When MOSFET (VT1) turns on ,the current flows through white LED and it connects with filter capacitor(C2),inductance (L1) and test resistor(R1) in series-parallel way.The current value is decided by test resistor value and test voltage threshold of ZXSC310(It's usually 19mV).
