High Voltage Switching Reaulator

●The MC33363A is a monolithic high voltage switching regulator that is specifically designed to operate from a rectified 240 Vac line source. This integrated circuit features an on–chip 700 V/1.5 A SenseFET power switch, 500 V active off–line startup FET, duty cycle controlled oscillator, current

●limiting comparator with a programmable threshold and leading edge blanking, latching pulse width modulator for double pulse suppression, high gain error amplifier, and a trimmed internal bandgap reference.
