MC33363B
High Voltage Switching
Regulator
The MC33363B 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
SENSEFETï 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, overvoltage protection, and thermal
shutdown. This device is available in a 16--lead dual--in--line and wide
body surface mount packages.
