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 on−chip 500 V/2.0 A
SENSEFET power switch, 250 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.
