UCC28781/UCC28781-Q1 ZVS Controller

Texas Instruments UCC28781/UCC28781-Q1 Zero-Voltage-Switching (ZVS) Controller can be used at very high switching frequencies to minimize the size of the transformer and enable high power density. With direct synchronous rectifier (SR) control, the controller does not need a separate SR controller, as it can drive the SR FET directly to maximize efficiency and simplify the design. (For isolated applications, an isolated gate-driver IC is required.)
