MC33363A_10 Datasheet, PDF (1/13 Pages) ON Semiconductor – High Voltage Switching Regulator

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.
