MC33363A/D
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
SENSEFET® 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.
