MC33363A
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
SENSEFETt 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.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
