Test Procedure
2.1
Hardware and Software Set Up
2.1.1
Power Supply
A power supply capable of supplying 2.2 V - 5 V, 3 A, is required. A short cable from the power supply to
the EVM input is recommended. If long line is a must, a 2,200-µF capacitor is suggested at the input for
better input supply stability.

better input supply stability.
2.1.2
Load
Use electronic load or other variable resistor to evaluate different load conditions.
2.1.3
Input Current Meters
The current meters must have low impedance when measuring the efficiency to decrease the voltage drop
affect. Placing a 2,200-µF capacitor at the input side of the EVM will guarantee the low impedance.

2.1.4
USB2ANY Communication Kit
The USB2ANY serves as an interface adapter between a host PC and a TPS65290 EVM. The
communication between the USB2ANY and the host PC is via USB, while the communication between the
USB2ANY and the TPS56290 EVM is via an SPI. The USB2ANY hardware is based on the TI
MSP430F5529 16bit Microcontroller with integrated USB 2.0.
