TLV61220EVM-120, Low-Input Voltage, Step-Up Converter
Evaluation Module
This user’s guide describes the characteristics, operation, and use of the TLV61220EVM-120 evaluation
module (EVM). This EVM demonstrates the Texas Instruments TLV61220 synchronous boost converter.
The input voltage range of the TLV61220 is 0.7 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.
