TPS61097EVM-498
This user's guide describes the characteristics, operation, and use of the TPS61097EVM-498 evaluation
module (EVM). This EVM demonstrates the Texas Instruments TPS61097 synchronous boost converter.
The input voltage range of the TPS61097 is 0.9 V to 5.5 V, allowing the device to operate from one-cell to
three-cell battery configurations in addition to a single-cell Li-ion battery. This user's guide includes setup
instructions, schematic diagram, bill of materials, and printed-circuit board layout drawings for the EVM.
The TPS61097EVM-498 evaluation module (EVM) helps designers evaluate the operation and
performance of the TPS61097 boost converter. The TPS61097 comes in fixed output voltage versions
described in Table 1 . The board features the small 5-pin SOT-23 package for a small solution size.
