Introduction
This section contains background information for the TPS61085EVM evaluation module.
1.1
Background
This TPS61085EVM uses a TPS61085 boost converter to step up 2.3 V to 6 V input voltages to 12 V. The
goal of the EVM is to facilitate evaluation of the TPS61085 power supply solution. The EVM uses the
TPS61085 adjustable output boost converter and the appropriate feedback components to provide 12 V.
