| Abstract: | A design method of the low-power switching power supply with synchronous frequency is presented.This kind of switching power has simple structure, self-adapting function which works from 110V to 220V wide range voltage with frequency of 50Hz and 60Hz, soft-starting function and constant voltage function.Then it can be used as the low-power supply with less than 2W output power. |
