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.

No Module Installed

Evaluation board can be used for the RGB and RGC Series.

*Power module installed is rated for 3.3V. Standard EV kit configuration allows operation to 3.6V. Contact support if lower voltage is needed.

**

Power module installed is rated for 0.8V. Standard EV kit configuration allows operation to 1.0V. Contact support if lower voltage is needed.

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.
