BUCK
BUCK circuit is a kind of DC-DC converter based on the principle of inductive energy storage, which involves the basic principles of electromagnetic induction and electric energy conversion in physics. In BUCK circuit, the DC voltage provided by the input power supply is converted to the adjustable low voltage output by controlling the on-on and off-state of the PWM wave switching tube with variable input duty ratio, so as to meet the power supply requirements of different circuits.
