Control Card for Digitally Controlled Isolated Power

Converters

1 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.

2 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 www.ti.com to check EVM status and availability.

• UCD3138PFCEVM-026, a digital controlled PFC pre-regulator evaluation board, Texas Instruments

Literature Number, SLUU885

• UCD3138PSFBEVM-027, a digital controlled phase-shift full-bridge DC-to-DC converter evaluation

board

• UCD3138LLCEVM-028, a digital controlled LLC resonant half-bridge DC-to-DC converter evaluation

board, Texas Instruments Literature Number, SLUU979

2.1 Typical Applications

• Isolated Power Supply Applications (such as single-phase, two-phase interleaved or bridgeless PFC,

LLC resonant half-bridge DC-to-DC power converter, phase-shifted full-bridge DC-to-DC power

converter, and hard switching full-bridge DC-to-DC power converter)

• Server Power Supplies and Telecom Rectifiers

• Isolated DC-to-DC Telecom Modules

Test Procedure

www.ti.com

7 Test Procedure

7.1 Download Firmware Codes to UCD3138CC64EVM-030

See Figure 5 to set up the EVM connection.

1. Set up the EVM connection based on Figure 5. The LED of USB adapter lights up.

2. Use the provided jumper jump across J2. The LED of the EVM lights up.

3. Launch the UCD31xx device GUI following the steps described in Section 6.1.3. The window shown in

Figure 6 appears.

4. Click Firmware Download and a new window appears as shown in Figure 7. Click Select File and

browse an intended firmware code file with file extension .x0, for example, cyclone.x0. Then click

Download. TI recommends not writing the program checksum (stay in ROM) during firmware

development or debug state. The firmware of cyclone.x0 downloads to the device UCD3138 on the

board of UCD3138CC64EVM-030. When asked, click yes to complete the download. Click Close to

exit the download window.

5. After the firmware codes download to the UCD3138 device, the intended test can be performed. For

example, with the provided firmware cyclone.x0, one can observe voltage toggled between 0 V and 3.3

V on test point TP7.

7.2 Erase Firmware Codes from UCD3138CC64EVM-030

Erasing the downloaded firmware codes from UCD3138 flash memory can be made with the steps below

based on Figure 6.

1. Click Device ID

2. Click Command Program to jump to ROM (SendByte.0xD9)

3. Click Erase/Set PFlash: 0xFF

7.3 Equipment Shutdown

1. Exit the GUI

2. Disconnect the USB cable and the ribbon cable
