Introduction
This UCD3138A64CEVM-660 evaluation module helps evaluate the UCD3138A64 digital controller device
from Texas Instruments and aids in design of digitally controlled isolated power converters. The
UCD3138A64 device belongs to the UCD3138 family of highly-integrated digital controller devices
optimized for isolated power supply applications. Compared to the UCD3138 device, the UCD3138A64
device offers the following features:

The UCD3138A64CEVM-660 is similar to the UCD3138CC64EVM-030. The UCD3138A64CEVM-660 is
used either as a stand-alone control card to study the UCD3138A64 controller IC 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 two
power converter EVMs offered by TI: UCD3138PSFBEVM-027, and UCD3138LLCEVM-028. Contact
Texas Instruments for assistance obtaining the firmware source code used to interface the UCD3138A64
with these EVMs, which were originally developed to support the UCD3138 device. Alternately, the EVM
can also be loaded with custom-developed firmware. In order to communicate with the UCD3138A64
digital controller in this EVM, a separate USB interface adapter 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. Texas Instruments also
offers a Graphical User Interface (GUI) in order to program the UCD3138A64 controller and configure
parameters when used with the two power converter EVMs.
