Buck regulator

A buck converter (step-down converter) is a DC-to-DC power converter which steps down voltage (while stepping up current) from its input (supply) to its output . Essentials about the circuit and operation of a step down or buck regulator using switch mode power supply techniques used in many power supplies and .

The switching transistor between the input and output of the Buck Converter continually switches on and off at high frequency. To maintain a continuous output, . The energy is buffered in a series inductor when the main . Buck regulators consist of two switches, two capacitors, and an inductor, as shown in Figure 2. Nonoverlapping switch drives ensure that only one switch is on at .

ST’s monolithic switching regulators offer input-voltage capability up to V, deliver output currents up to A, with high switching frequency.
