December 13, 2021 v1 Evaluation Board Manual –i3A/i6A Series 2 / 10 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 i3A / i6A 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. Evaluation Kit Part Number Non-Isolated DC-DC Module (Included and Mounted on the Evaluation Board) DC-DC Module Part Number Type I/P Range O/P Range O/P Current (max) O/P Power (Max) i3A05A-C01-EVK-S1 i3A4W005A150V-001-R Buck 9 – 53 V 5.0 – 30 V 4.5 A 100 W i3A08A-C01-EVK-S1 i3A4W008A033V-001-R Buck 9 – 53 V 3.3* – 16.5 V 8 A 100 W i6A10A-C01-EVK-S1 i6A4W010A033V-001-R Buck 9 – 53 V 3.3* – 40 V 10 A 250 W i6A14A-C01-EVK-S1 i6A24014A033V-001-R Buck 9 – 40 V 3.3* – 24 V 14 A 250 W i6A20A-C01-EVK-S1 i6A4W020A033V-001-R Buck 9 – 53 V 3.3* – 15 V 20 A 250 W i367X-C01-EVK-S0 Evaluation board with no module installed. * Evaluation kit output trim adjustment configuration is limited to 3.6 V minimum. Contact technical support at powersolutions@us.tdk- lambda.com 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 i7A / i7C 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.

December 13, 2021 v1 Evaluation Board Manual –i3A/i6A Series 3 / 10 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.
