Based on the 0.6μm BCDMOS process a hysteretic-current-control mode white light LED driver with high accuracy and efficiency is presented.The driver can work with a 6-40 V power supply,the maximum output current is up to 1.0 A,the maximum switching frequency is up to 1 MHz,the output current error is less than±5%,and the efficiency is greater than 80%.The circuit details of the high-side-current sensor and high-speed comparator,which greatly affect the accuracy of the whole driver,are emphasized.Then,the simulation and test results of this work are presented.
