UCD3138A64 Control Card Evaluation Module


Order now


The Texas Instruments UCD3138A64CEVM-660 evaluation module (EVM) functions as a control card for UCD3138A64 digital controller for isolated power applications from Texas Instruments. The EVM can be used either as a stand-alone board to study the UCD3138A64 device or as a control card for implementing a fully regulated power converter based on topologies such as a Half-Bridge Resonant LLC, and Phase Shift Full-Bridge. This is implemented by downloading the appropriate firmware into the UCD3138A64 device in the EVM and establishing interface with a suitable power stage board from the end user.

In order to assist in the evaluation of common isolated power topologies, the UCD3138A64CEVM-660 evaluation module has been designed to interface seamlessly with the UCD3138LLCEVM-028 Digital LLC Half-bridge DC/DC Converter EVM, and the UCD3138PSFBEVM-027 Digital Phase-Shifted Full-Bridge DC/DC Converter EVM also available from Texas Instruments.

NOTE: In order to download firmware and program the UCD3138A64 controller in UCD3138A64CEVM-660, a separate EVM from Texas Instruments known as the USB-TO-GPIO Adapter is required. The USB-TO-GPIO Adapter is NOT supplied with UCD3138A64CEVM-660 evaluation module and must be purchased separately. The USB-TO-GPIO Adapter serves as a communication interface adapter or a bridge between a host PC (IBM compatible) and one or multiple slave devices via a standard type-A to mini-B USB cable. The USB-TO-GPIO Adapter is listed below in the related products section.

  • UCD3138A64PFC digital controller PMBus Connector to interface with USB-to-GPIO Adapter, for communication with host PC
  • Includes On-board SPI and I2C accessible EEPROMs for additional memory storage
  • 40-pin Digital Signal Connector to Connect Digital Signals to Power Converters
  • 40-pin Analog Signal Connector to Connect Analog Signals to Power Converters
  • LED Indicator
  • Rich Test Points to Facilitate the Device Evaluation, System Design and Circuit and Firmware Debugging
