Product Summary

The TDA4718A is a Switched-Mode Power Supply. The versatile SMPS control ICs comprise digital and analog functions which are required to design high-quality flyback, single-ended and push-pull converters in normal, half-bridge and full-bridge configurations. The component can also be used in singleended voltage multipliers and speed-controlled motors. Malfunctions in electrical operation are recognized by the integrated operational amplifiers, which activate protective functions.
