Description

These isolated gate drivers require their isolated bias supplies to be low cost, high reliability, low EMI, and immune to high CMTI (Common Mode Transient Immunity). UCC25800open-loop LLC transformer driver is designed to meet these design challenges and provides a robust, costeffective, and low EMI solution for isolated gate driver bias. This application note introduces the LLC topologyand the benefits of using LLC for isolated gate driver bias supplies. It also provides the design guidelines tosimplify the design process.
