Many significant circuit enhancements that reduce the sensitivity to board layout and line transients now make the design even easier. TOPSwitch incorporates all functions necessary for a switched mode control system into a three terminal monolithic IC are power MOSFET, PWM controller, high voltage start up circuit, loop compensation and fault protection circuitry.
