Application about TOPSwitch-GX Device in Switching Power Supply
Yang Shu-xi · Power Supply Technologies and Applications · 2002
TOPSwitch-GX device is a new type IC merging PWM and MOSFET into one. It uses the same circuit as TOP-Switch, expands the power range of TOPSwitch device and integrates many new functions. A kind of closed power supply made of TOP249Y is introduced, the line sense function and external current limit function of TOPSwitoh-GX are used. This design is novel and has some practical value.
