MC33363A

MC33363A High Voltage Switching Regulator 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 SENSEFET® 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. This device is available in a 16−lead dual−in−line and wide body surface mount packages. www.onsemi.com MARKING DIAGRAMS 16 1 SO−16W DW SUFFIX CASE 751N MC33363ADW AWLYYWWG Features Enhanced Power Capability Over MC33363 On−Chip 700 V, 1.5 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 Output Overvoltage Protection Comparator Trimmed Internal Bandgap Reference Internal Thermal Shutdown These are Pb−Free Devices* A = Assembly Location WL = Wafer Lot YY = Year WW = Work Week G = Pb−Free Package PIN CONNECTIONS Startup Input 1 16 Power Switch Drain VCC 3 AC Input Regulator Out...
