3S0680RF

800V, 6A Fairchild Power Switch (FPS) Controller IC, combining an internal high-voltage current-sensing power MOSFET with a pulse-width modulation (PWM) controller block on a single substrate. It functions as a robust off-line switched-mode power supply (SMPS) regulator featuring low standby power consumption, housed in a 5-pin through-hole plastic power package with an isolated mounting tab.
