MC33363B High Voltage Switching Regulator
The MC33363B 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/1.0 A SENSEFETt 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, overvoltage protection, and thermal shutdown. This device is available in a 16-lead dual-in-line and wide body surface mount packages. · On-Chip 700 V, 1.0 A SENSEFET Power Switch · Rectified 240 Vac Line Source Operation · On-Chip 500 V Active Off-Line Startup FET · Latching PWM for Double Pulse Suppression · Cycle-By-Cycle Current Limiting · Input Undervoltage Lockout with Hysteresis · Over-Voltage Protection · Trimmed Internal Bandgap Reference · Internal Thermal Shutdown
