Introduction
This evaluation kit has been designed to provide an easy way to characterize the product’s performance and its features. It is intended to aid customers and determine the product’s 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) 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 need to be verified at the customer’s end, system level.

The installed power module can be adjusted to 3.3V. The standard EV kit configuration supports operation down to 3.6V. Contact technical support if a lower voltage is needed. The installed power module can be adjusted to 0.8V. The standard EV kit configuration supports operation down to 1.0V. Contact technical support if a lower voltage is needed.
IMPORTANT INFORMATION
- Observe proper safety and laboratory procedures when testing electronic products. This list serves as a 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 in 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 loads. 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 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 products or equipment.
- Please check the pertinent product (DC-DC Module) datasheets and specifications for complete information.
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 that the output capacitor value may need to be adjusted to meet the transient response or ripple requirements of the final application. Refer to the product data sheet for a range of acceptable values.
| Test Point | Description | Test Point | Description |
| TP1 | Vin (+) | TP8 | SENSE + |
| TP2 | Vin (-) / GND | TP9 | PGOOD : Only for i7C |
| TP3 | Not Populated | TP10 | Vout (+) |
| TP4 | ON / OFF | TP11 | Vout (-) / GND |
| TP5 | SYNC: Only for i7C
(Frequency Synchronization) |
TP12 | Vout (+) – for Output Ripple Measurement |
| TP6 | I_MON: Only for i7C
(Output Current Monitor) |
TP13 | Vout (-) / GND – for Output Ripple Measurement |
Note: Depending on the model series (e.g., i7C, i7A), not all Test Points (TP) are applicable. Please double-check the individual product series datasheets for the features that it supports.
| Screw Terminal | Description | Screw Terminal | Description |
| J1 | Vin (+) | J3 | Vout (+) |
| J2 | Vin (-) / GND | J4 | Vout (-) / GND |
Turn-on / Turn-off module by switch
Change the position of the toggle switch” S1” to “CLOSE” to turn on the power supply unit.
Change Output Voltage
Turn screw on trimmer pot “VR1” to change the output voltage.- Turn clockwise to decrease the output voltage.
- Turn counterclockwise to increase output voltage.
When using an external clock (SYNC function only for i7C)
SYNC function default setting is disabled. Please remove resistor ”R14” on the bottom side of the board to enable the SYNC function.
Capture the output ripple/noise waveform
Please use TP12 and TP13 to measure output ripple/spike.- Wired GND clip may pick up higher spike noise.
- Use the bare probe to minimize spike noise.
- Please ensure proper polarity when connecting.
- TP12 is Vout (+) / TP13 is GND.
Mechanical Outline – i7CxxA-C03-EVK-S1
The overall height for the evaluation kit, pn: I7C20A-C03-EV 1, can vary up to 41.5 ±1.5 mm [1.63 ± 0.06 in]. Specific height depends on the type of module installed, whether it’s an open frame, heats, ink, or baseplate version.
