Order this document by MC33363B/D 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 Sense FET power switch, 450 V active off- line startup FET, duty cycle controlled oscillator, current limiting parator 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 Sense FET Power Switch HIGH VOLTAGE OFF- LINE SWITCHING REGULATOR SEMICONDUCTOR TECHNICAL DATA 16 1 - - - - - - - - Rectified 240 Vac Line Source Operation On- Chip 450 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 DW SUFFIX PLASTIC PACKAGE CASE 751N (SOP- 16L) 16 1 Simplified Application P SUFFIX PLASTIC PACKAGE CASE 648E (DIP- 16) AC Input Startup Input Regulator Output 8 6 RT CT Osc 7 PWM Latch S Q PWM R Ipk Thermal LEB pensation 9 EA 10 Voltage Feedback Input Driver OVP Startup Reg UVLO VCC 3 Overvoltage Protection Input 11 16 Power Switch Drain DC Output 1 PIN CONNECTIONS Startup Input 1 16 Power Switch Drain Mirror VCC Gnd 3 4 5 13 Gnd 12 11 10 9 (Top View) Overvoltage Protection Input Voltage Feedback Input pensation 6 7 8 RT CT Regulator Output ORDERING INFORMATION Device MC33363BDW MC33363BP Operating Temperature Range TJ = - 25° to +125°C Package SOP- 16L DIP- 16 Rev 1 Gnd 4, 5, 12, 13 © Motorola, Inc....
