MC33363A: High Voltage Switching Regulator
For complete documentation, see the data sheet
Product Description
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 MOSFET 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.
