MC33363A - High Voltage Switching Regulator

1 Semiconductor Components Industries, LLC, 2015 January, 2015 Rev. 91 Publication Order Number: MC33363A /DMC33363 AHigh Voltage SwitchingRegulatorThe MC33363A is a monolithic high Voltage Switching regulatorthat is specifically designed to operate from a rectified 240 Vac linesource. This integrated circuit features an on chip 700 V / ASENSEFET power switch, 500 V active off line startup FET, dutycycle controlled oscillator, current limiting comparator with aprogrammable threshold and leading edge blanking, latching pulsewidth modulator for double pulse suppression, high gain erroramplifier, and a trimmed internal bandgap reference.

2 Protectivefeatures include cycle by cycle current limiting, input undervoltagelockout with hysteresis, output overvoltage protection, and thermalshutdown. This device is available in a 16 lead dual in line andwide body surface mount Enhanced Power Capability Over MC33363 On Chip 700 V, 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*Figure 1.
