The picture shows a small power mini switch regulated power supply made by WS157 and WS106. WS157 and WS106 are a type of control component in regulated power supply. This kind of component integrates control circuit and power switch on the same chip which has the PWM controlling function and over current and over heat test function. It needs suitable switch transformer and some components to keep steady work situation. The regulate power supply made by it can directly convert the DV 220 V to low DC voltage. And the power of WS157 is 18 W while the power of WS106 is 12 W.
