SLUU886–February2012 Control Card in a Digitally Controlled Off-Line Isolated

Power Converter

1Introduction

This UCD3138CC64EVM-030evaluation module is to help evaluate the UCD3138device from Texas

Instruments and aid in the design of digitally controlled isolated power converters.The EVM can be used

either as a stand-alone control card to study the UCD3138controller 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-026power converter EVM offered by TI.Alternately the EVM can also be loaded with

user’s custom developed firmware.In order to communicate with the UCD3138digital 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 UCD3138CC64EVM-030evaluation

module and must be purchased separately.Texas Instruments also offers a Graphical User Interface in

order to program the UCD3138controller and configure parameters when used with the power converter

EVM mentioned above.

2Description

UCD3138CC64EVM-030is 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.The EVM works seamlessly

with the following EVM board,together with corresponding firmware,all developed by Texas Instruments.
