摘要：
A new hysteresis-current-controlled buck converter with alternating current (AC) sensing techniques is presented in this Letter. The proposed AC sensing technique senses the inductor current ripple by sensing the voltage at two terminals of the inductor. Accompanying with hysteresis-current-controlled technique and a type-III compensator, the transient response can be accelerated. The simulation result shows the response time is 0.7 mu s when the load current switch from 150 to 600 mA and the maximum efficiency is 94.6%.
