Introduction
This EVM, UCD3138LLCEVM-028 is to help evaluate the UCD3138 64-pin digital control device in an off-
line power converter application and then to aid in its design. The EVM is a standalone LLC resonant half-
bridge DC-to-DC power converter. The EVM is used together with its control card, UCD3138CC64EVM-
030, also an EVM on which is placed UCD3138RGC.

The UCD3138LLCEVM-028 together with UCD3138CC64EVM-030 can be used as they are delivered
without additional work, from either hardware or firmware, to evaluate an LLC resonant half-bridge DC-to-
DC converter. This EVM combination allows for some of its design parameters to be retuned using a GUI
based tool, called Texas Instruments Fusion Digital Power Designer. It is also possible to load custom
firmware with user’s own definition and development.

• An isolated DC voltage source meeting IEC61010 reinforced
insulation standards is recommended for evaluating this EVM.
• High temperature exceeding 60°C may be found during EVM
operation and for a while even after power off.
• This EVM’s purpose is to facilitate the evaluation of digital
control in an LLC using the UCD3138, and cannot be tested
and treated as a final product.
