Switching Regulator Control Circuits
Very High Voltage Switching Regulator
MC33362DW, P
T J = –25 to +125 C, Case 751N, 658E
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
