This integrated circuit features an on–chip 700 V/1.0 A SenseFET power switch, 450 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 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 Simplified Application Startup Reg Osc Thermal LEB PWM DC Output Startup Input Gnd 4, 5, 12, 13 Mirror 7 AC Input Regulator Output 6 8 CT RT PWM Latch EA Ipk VCC 3 11 16 9 10 1 Compensation Voltage Feedback Input Power Switch Drain Overvoltage Protection Input Driver OVP UVLO S R Q © Motorola, Inc. 1999 Rev 1 |
