Several commonly used design methods program of three kinds of circuit modes :
DC/DC power conversion regulator regulator, linear (analog) regulator, DC/DC switching regulator
① It should be noted that the regulator circuit can not be used to make power supply, can only be used for chip power supply requirements;
②the circuit structure of linear regulator circuit is simple, but because of low conversion efficiency, it can only be used for low-power power supply
③ switch-mode regulator circuit, high conversion efficiency, can be used in high-power applications, but its limitations in the circuit structure is relatively complex (especially high-power circuits), is not conducive to miniaturization
Therefore, , we should choose the right design according to the actual in the design process.
