Abstract : Understanding Buck Power Stages In Switchmode Power Supplies
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.
