HIGH VOLTAGE

OFF–LINE

SWITCHING REGULATOR

The MC33365 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/1.0 A SenseFET power switch,

450 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. Protective

features include cycle–by–cycle current limiting, input undervoltage lockout

with hysteresis, bulk capacitor voltage sensing, and thermal shutdown. This

device is available in a 16–lead dual–in–line package.
