4.2 Hardware Requirement
This EVM requires an external power supply capable of providing 4.5 V to 18 V at 6 A.
The EVM kit includes USB2ANY interface box which, when installed on a PC and connected to the EVM, permits
communication with the EVM via a GUI interface. The minimum PC requirements are:
• Microsoft ® Windows ® 2000, Windows XP, or Windows 7 operating system
• USB port
• Minimum of 30MB of free hard disk space (100MB recommended)
• Minimum of 256MB of RAM
4.3 Hardware Setup
After connecting the power supply to J6 and turning on the power supply, the EVM regulates the output voltages
to the value listed in
Table 1-1 . Additional input capacitance may be required in order to mitigate the inductive
voltage droop that may occur during a load transient event.
In order to change the output voltage by sending the digital control signal via a PC running the TPS65400
controller software and USB2ANY interface box, perform the following steps:
1. Connect the USB port of USB2ANY to the PC using the USB cable and the other end to J13 of the
TPS65400 using the supplied 30-pin ribbon cable ( Figure 4-2 ). The connectors on the ribbon cable are
keyed to prevent incorrect installation.
2. Connect the power supply on J6 and turn on the power supply.
3. Run the software as explained in
Section 4.4 .
