Evaluation Board Manual – i7X Series
2 / 11
1. Introduction
This evaluation kit has been designed to provide an easy way to characterize the product performance and its features.
It is intended to aid customers and determine the product suitability for the target application. The evaluation board
incorporates the required external components to demonstrate the complete product functionality. It also includes other
components (e.g. test points, etc…) to facilitate a successful end user experience. Not all these external components
are required if the product features are not needed. Details of the external components, schematics, and PCB layout
are provided in this documentation for reference only. Final design and qualification needs to be verified at customer’s
end system level.
2. Ordering Information
TDK-Lambda offers a wide variety of non-isolated dc-dc power modules in the i7X series. Not every product is currently
available in an evaluation kit. The table below includes description and ratings which should help in selecting the most
applicable evaluation kit.

IMPORTANT INFORMATION
•
Observe proper safety and laboratory procedures when testing electronic products. This list serves as general guide
only and not a substitute for common sense and best practices.
•
Before applying power, double check and ensure all connections to the evaluation board interface are correct (e.g.
Input source polarity connections, etc…).
•
This evaluation board is not populated with an input fuse. An input fuse can be populated in PCB location F1. Check
the product specifications for the input fuse ratings and the evaluation board schematics included this manual. Make
sure the existing jumper connections, BB4 and BB5, are removed when adding the fuse.
•
Although highly efficient, these high power density modules can dissipate significant amounts of power, especially at
heavy load. Care should be taken to ensure adequate cooling is provided and the modules are operated within the
thermal specifications outlined in the product data sheets. Heat sink and base plated versions of the i7X family are
available for use in demanding environments.
•
This evaluation kit is designed for general laboratory use. It is not intended for installation in end customer product or
equipment.
•
Please check the pertinent product (DC-DC Module) datasheets and specifications for complete information.
