MC33365
High Voltage Switching
Regulator
is specifically designed to operate from a rectified 240 Vac line source.
This integrated circuit features an on−chip 700 V/1.0 A SENSEFETt
power switch, 450 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, bulk capacitor
voltage sensing, and thermal shutdown. This device is available in a
16−lead dual−in−line package.
