Introduction

The Texas Instruments TPS61090EVM evaluation board helps designers

evaluate the operation and performance of the TPS61090 family of

high-frequency synchronous boost DC/DC converters.

This EVM is specifically designed and optimized to operate with 2-cell NiCad,

Ni-MH, or alkaline battery input. The default output voltage of this EVM is 5.0V.

If desired, this EVM can easily be modified to supply higher or lower output

voltages by adjusting the appropriate feedback resistor dividers. Also, other

fixed-output voltage versions of the devices can be easily evaluated using this

EVM. Refer to the product data sheet (SLVS484) for the various fixed-output

voltage options available in the TPS6109x device family as well as for more

information on adjusting the output voltage.
