EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of 0.9 V to 6 V and output

voltage range of 1.8 V to 5.5 V.

Exceeding the specified input range may cause unexpected operation and/or irreversible

damage to the EVM. If there are questions concerning the input range, please contact a TI

field representative prior to connecting the input power.

Applying loads outside of the specified output range may result in unintended operation and/or

possible permanent damage to the EVM. Please consult the EVM User’s Guide prior to

connecting any load to the EVM output. If there is uncertainty as to the load specification,

please contact a TI field representative.

During normal operation, some circuit components may have case temperatures greater than

60°C. The EVM is designed to operate properly with certain components above 60°C as long

as the input and output ranges are maintained. These components include but are not limited

to linear regulators, switching transistors, pass transistors, and current sense resistors. These

types of devices can be identified using the EVM schematic located in the EVM User’s Guide.

When placing measurement probes near these devices during operation, please be aware

that these devices may be very warm to the touch.

Introduction



The Texas Instruments TPS61020 evaluation module (EVM) for low-power,

high-efficiency, boost converter helps designers evaluate the TPS61020

device. The EVM makes it possible to evaluate different device modes as well

as the device performance.

The TPS61020EVM is set to 3.3 V. The TPS61020EVM can be easily set up

to provide any output voltage between 1.8 V and 5.5 V by adjusting the external

resistor divider. Refer to the datasheet (SLVS451) for the output voltage

calculation. The TPS61020 has an input voltage range between 0.9 V and

6.5 V.
