Texas Instruments  UCD3138ALLCEVM150

UCD3138ALLCEVM150 is an EVM board, functioning as an LLC resonant half-bridge dc-dc converter and digitally controlled by control card UCD3138ACCEVM149. This EVM is used to evaluate digital power control using UCD3138A in LLC resonant half-bridge dc-dc conversion applications. The EVM accepts the dc line input from 350Vdc to 400Vdc, nominal output voltage 12Vdc, and output full load power 340W with peak efficiency over 94% benefited from secondary side synchronous rectifier operation. The EVM is featured with various protections such as input line under voltage, output over-voltage and over-current limit, soft start, and light load power losses reduction. The EVM can be used as a platform to upload user’s firmware and adapt particular needs. The EVM comes with USB-TO-GPIO interface adapter and is shipped with the control card UCD3138ACCEVM149 pre-programmed with the LLC resonant half-bridge dc-dc converter firmware developed by Texas Instruments.
