Introduction
The UCD3138CC64EVM-030 evaluation module helps evaluate the UCD3138 device made by Texas
Instruments and aids in the design of digitally controlled isolated power converters. The EVM can be used
either as a stand-alone control card to study the UCD3138 controller device, or as a DPWM controller
board working with a power-stage board to implement a fully regulated power converter. To help the
targeted off-line isolated power applications, this EVM has been designed to work seamlessly with the
UCD3138PFCEVM-026, UCD3138PSFBEVM-027, and UCD3138LLCEVM-028 power-converter EVMs
offered by TI.

Alternately the EVM can also be loaded with custom user-developed firmware. In order to communicate
with the UCD3138 digital controller in this EVM, a separate USB Interface Adapter EVM from TI known as
the USB-TO-GPIO Adapter is required. The USB-TO-GPIO adapter is NOT supplied with
UCD3138CC64EVM-030 evaluation module and must be purchased separately. TI also offers a Graphical
User Interface (GUI) in order to program the UCD3138 controller and configure parameters when used
with the power-converter EVMs mentioned above.

Description
The UCD3138CC64EVM-030 is an EVM board, functioning as a control card for UCD3138RGC digital
power-supply applications. This EVM is used to control a power-converter topology such as PFC pre-
regulator, LLC Resonant Half-Bridge DC converter, and Phase-Shifted Full-Bridge DC converter by
downloading the associated firmware and interfacing with an appropriate power stage board. After the
UCD3138 is programmed appropriately, the EVM works seamlessly with the following EVM boards from
Texas Instruments. Please visit
