The research and design of TOPSwitch power supply system
Abstract: The TOPSwitch switch power supply is three line the type PWM switches, the its characteristics the is to the gather the controller of the PWM and the MOSFET the power switch the tube within the high the switch the power supply the on same chip, the simplified the power supply the electric circuit the thus and consumedly, the raise the credibility, make the design of the power supply is fast more and in brief. This article elaborated the TOPSwitch concept and the function character, and put forward the design that aims at the high frequency switch power supply of chip of TOPSwitch. The article involved some basic knowledge of a switch power supply, and designed the in general use switch power supply of concrete applied 250 Ws to TOPSwitch machine piece, still involving the cloth line of the PCB version and to the high frequency power supply electric circuit electromagnetism and permit excellent to turn.
