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.

I7X-C01-EVK-S1 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.

3. General Features
Screw Terminals for secured input and output connections
Toggle switch for Remote ON/OFF
Test points / Scope probe hook-ups for ease of measurement
Trim Potentiometer for adjusting the output voltage setting
Component PCB pad provisions for: Input fuse, input inductor, additional input and output capacitance*, output
header connector for optional features and signals.
* Note the output capacitor value may need to be adjusted to meet transient response or ripple requirements of the final
application. Refer to product data sheet for a range of acceptable values.

4. Turn-on / Turn-off module by switch
Change position of toggle switch”S1” to “CLOSE” turns-on the power
supply unit.
5. Change Output Voltage
Turn screw on trimmer pot “VR1” to change the output voltage.
Turn clockwise to decrease output voltage.
Turn counter clockwise to increase output voltage.
6. When using external clock (SYNC function only for i7C)
SYNC function default setting is disabled. Please remove
resistor ”R14” on bottom side of the board to enable the
SYNC function.
7. Capture output ripple/noise waveform
Please use TP12, TP13 to measure output ripple/spike.
Wired GND clip may pick up higher spike noise.
To use bare probe minimize spike noise.
Please pay attention for connect right polarity.
TP12 is Vout (+) / TP13 is GND.
