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.

• On−Chip 500 V, 2.0 A SENSEFET Power Switch
