摘要：
This paper presents an asynchronous 1MHz DC-DC boost converter for TFT LCD power supply, using a pulse-width-modulated peak current mode controller. Both complete small signal analysis and overall efficiency investigation of the boost converter are performed, as well as the discussion of compensation method. An error amplifier with a compensation network and a sum-comparator with three input channels are proposed. A maximum power conversion efficiency of higher than 90% is achieved.
