... Vref Idelay Vsd Vcc Vovp ©2003 Fairchild Semiconductor Corporation Description The Fairchild Power Switch (FPS) product family is specially designed for an off line SMPS with minimal external compo- nents. The Fairchild Power Switch (FPS) consists of high volt- age power SenseFET and current mode PWM controller. The ...

FS7M0680 Vo Pulse by pulse current limit Figure 3 shows the pulse-width-modulation (PWM) block of the FPS. Since the FPS employs the peak current mode con- trol, the current through the power MOSFET is limited by the inverting input voltage ...
