TDA4718

Control IC for Single-Ended and Push-Pull Switched-Mode Power Supplies (SMPS) TDA 4700 TDA 4718 Features q Feed-forward control (line hum suppression) q Symmetry inputs for push-pull converter (TDA 4700) q Push-pull outputs q Dynamic output current limitation q Overvoltage protection q Undervoltage protection q Soft start q Double pulse suppression P-DIP-24-1 Type Ordering Code Package Temp.-Range TDA 4700 A Q67000-Y594 P-DIP-24-1 – 0 to 70 °C s TDA 4718 A Q67000-Y639 P-DIP-18-1 – 0 to 70 °C s Not for new design These versatile SMPS control ICs comprise digital and analog functions which are required to design highquality flyback, single-ended and push-pull converters in normal, half-bridge and full-bridge configurations. The component can also be used in single-ended voltage multipliers and speed-controlled motors. Malfunctions in electrical operation are recognized by the integrated operational amplifiers, which activate protective functions. P-DIP-18-1 1) Is now avail...
