Advance Information
High Voltage Switching
Regulator
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. Protective
features include cycle–by–cycle current limiting, input undervoltage lockout
with hysteresis, output overvoltage protection, and thermal shutdown. This
device is available in a 16–lead dual–in–line and wide body surface mount
packages.
