The UCC25630-3DDBR with Switching Controllers LLC Resonant is a controller manufactured by Texas Instruments. It is used to enable resonant half-bridge topologies with a variety of secondary-side rectifier configurations, monitor secondary-side current and voltages, protect the secondary-side components, and provide a wide range of system performance options. The controller offers advanced analog signal processing techniques to provide accuracy, reliability, and flexibility when operating continuous BOM. It includes a proprietary switching system that includes PFC, LLC, or Buck plus Synchronous Rectifier combinations, and also provides for seamless auto-transitions between CCM, DCM, or PMM operating modes. The controller also features a digital current control loop that allows for reliable operation without compromising efficiency or system performance. The device also comes with a variety of protection features such as OCP, OVP, UVP, and OTP, to ensure reliable operation. Additionally, the device is available in a 28-pin TSSOP package for easy integration into end applications.
