A High-Low Side Current Sense Circuits for High Power LED Driver
A high-low side current sense circuits for high power LED driver are designed.The two current sense circuits can switch freely according to application system.The two current sense circuits also can be used in boost topology,buck topology and boost-buck topology,etc.The circuit is implemented in CSMC 0.6μm 60V BCD process.The test results show that LED current is 371.3mA with 1.217V VREF.So the sense circuit is feasible.
