Install GUI file located on EVAL Kit Landing page (https://www.kinet-ic.com/ ktb8400aedaa-mmev01/). 2. Check the Jumpers for default setting. 3. Connect one pair of power cables to the connector of EVAL Kit at VIN and GND. 4. Before connecting the EVAL Kit to the VIN bench supply, turn on the supply and adjust the voltage as close to 0V as possible. Then turn off the supply. While off, connect the power cables ends to the VIN bench supply. 5. Turn on the VIN bench supply and very slowly ramp its voltage to an appropriate voltage, such as 3.6V. While ramping VIN slowly, use the bench supply's output current indication (or a digital multimeter) to monitor the VIN current. If the current becomes high, reduce the VIN voltage quickly to prevent damage. Then inspect the setup for any wiring errors. 6. To hardware shutdown the buck regulator, simply use a jumper at P2 to connect EN to GND. 7. Connect a voltage meter to the output KVOUT and KGND test pins, it should measure the voltage of the buck regulator, which is specified on Page 4 of the datasheet. Graphical User Interface (GUI) · Download and install GUI software located on EVAL Kit Page (https://www.kinet-ic.com/ ktb8400aedaa-mmev01/). · After installing software, the interface will appear with the status message "USB Device Attached" at the bottom left side of the window. · If the displayed message is "USB Device Detached", make sure the computer is properly connected to the board. April 2024 EUM-0028-01 Page 3 of 9 Kinetic Technologies Confidential EVAL Kit Manual KTB8400 Additional Test Procedures to Program KTB400 Using I2C Pins 1. Take out P1 and P3 connectors. 2. Connect SDA, SCL and GND from the USB Adapter (Adafruit MCP2221A) to connector Logic Pins CN1. 3. Connect the USB end of the Adapter to the USB port of the computer. 4. Connect a DC power supply between the EVB test points VIN and GND. 5. With the power supply output turned off, configure the voltage to 3.6V. 6. Connect a voltage meter between the KVOUT and KGND. 7. Turn on the power supply output. 8. Start the "KTB8400 Control Panel" GUI program on the computer. 9. Verify that the USB Adapter has been detected in the GUI. 10. In order to establish the I2C communication, you need to type in the corresponding slave address for the IC under test. Please check KTB8400 datasheet (page 4) for the pre-defined address. Some of them can be found in the table below: Part Number KTB8400AEDAA-TR 7-bit I2C Slave Address 1100 000=0x60h April 2024 EUM-0028-01 Page 4 of 9 Kinetic Technologies Confidential EVAL Kit Manual KTB8400 Typical Test Setup Diagram As an example, use the following test setup to measure input/output in the Quick Start Procedures.

Also, connect current meter in series to input voltage source and output load. The efficiency can be determined using equation: Efficiency (%) = [ (V_out x I_out) / (V_in x I_in )] x 100% Low Inductance Probe Connection April 2024 EUM-0028-01 Page 8 of 9 Kinetic Technologies Confidential EVAL Kit Manual KTB8400 Important Notices Legal notice Copyright © Kinetic Technologies.
