[转贴]Understanding Buck Power Stages in Switchmode Power Supplies

sep_wq

TI的资深工程师写的，对于了解Buck（DC-DC step down）converter很有帮助，非常好的资料，在TI网站上可以找到，这里只卖1RD！

简介:
A switching power supply consists of the power stage and the control circuit. The power stage performs the basic power conversion from the input voltage to the output voltage and includes switches and the output filter. This report addresses the buck power stage only and does not cover control circuits. Detailed steady-state and small-signal analysis of the buck power stage operating in continuous and discontinuous mode are presented. Variations in the standard buck power stage and a discussion of power stage component requirements are included.
