MC33362
High Voltage Switching
Regulator
The MC33362 is a monolithic high voltage switching regulator that
is specifically designed to operate from a rectified 120 VAC line
source. This integrated circuit features an onchip 500 V/2.0 A
SENSEFETpower switch, 250 V active offline 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 cyclebycycle current limiting, input undervoltage
lockout with hysteresis, output overvoltage protection, and thermal
shutdown. This device is available in a 16lead dualinline 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.
