The switch regulated power supply control is classified into two types, which are the PWM type and FM type, and in the daily application, the former is used more often. In the switch power supply integrated circuits developed and used nowadays, the PWM takes the main part. Therefore, the following is mainly introducing the PWM switch regulated power supply. The basic working principle circuit of the switch regulated power supply is referred in the figure. To a single pole rectangle pulse, the DC average voltage Uo is determined by the width of the pulse, the wider the pulse is, the higher the DC average voltage value will be.
