TDA4714C

IC for Switched-Mode Power Supplies (SMPS) TDA 4714 C TDA 4716 C Bipolar IC Features q q q q q q q q q q Push-pull outputs (open collector) Double pulse suppression Dynamic current limitation Overvoltage protection IC undervoltage protection Reference voltage source Reference overload protection Soft start Feed-forward control Operational amplifier (TDA 4716 C) P-DIP-14-1 P-DIP-16-1 Type s TDA 4714 C s TDA 4716 C s Not for new design Ordering Code Q67000-A8312 Q67000-A8313 Package P-DIP-14-1 P-DIP-16-1 These versatile SMPS ICs comprise digital and analog functions which are required to design high-quality flyback, single-ended, and push-pull converters in normal, halfbridge and full-bridge configurations. The components can also be used in single-ended voltage multipliers and speed-controlled motors. Malfunctions in electrical operation are recognized by the integrated op amps which activate protective functions.
