Understanding Buck Power Stages In Switchmode Power Supplies
PDF, 173 Kb, File published: Mar 4, 1999
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
