The versatile switch-mode power supply ICs for the direct control of SIPMOS power transistors comprise digital and analog functions. These functions are required for the design of high-quality flyback and forward converters during single-phare and push-pull operation in normal, half-bridge and full-bridge configurations.

A versatile switch-mode power supply (SMPS) IC refers to an integrated circuit that provides the functionality and features required for creating efficient and flexible power supply solutions. These ICs are designed to regulate and convert electrical power efficiently, typically from a higher voltage source to a lower voltage output.

Versatile SMPS ICs are commonly used in a wide range of applications, including consumer electronics, industrial equipment, telecommunications, automotive electronics, and more.
