Every switching power supply is built around three classic non-isolated topologies: Steps voltage down. Boost Converter: Steps voltage up.
The core of any switching power supply is the power stage, which consists of energy storage elements like inductors and capacitors, and semiconductor switches. The topology of this stage—whether buck, boost, or buck-boost—dictates how the input voltage is transformed. Design begins with selecting the appropriate topology based on the required output voltage and current. For instance, a buck converter steps down voltage by chopping the input into pulses and filtering them through an LC network. The efficiency of this process is governed by the switching frequency; higher frequencies allow for smaller components but introduce greater switching losses and electromagnetic interference (EMI). fundamentals of power supply design mammano pdf link
