TPS6126x, Low-Input Voltage, Boost Converter Evaluation
Module
This user’s guide describes the TPS6126x evaluation module (EVM) and how to perform a stand-alone
evaluation to allow the EVM to interface with the system and host. The TPS61260EVM-673 converter is
programmed from the factory to deliver a 3.3-Vdc output voltage for a continuous load of up to 100 mA.
The boost converter can be enabled or disabled with the JP1 shunt jumper. Other options with a fixed
output voltage are available.
