This section contains background information for the TPS61175EVM-326 evaluation module.
This TPS61175EVM-326 is designed to boost 5.0 V to 12.0 V input voltages to a 24-V output. The goal of
the EVM is to facilitate evaluation of the TPS61175 power supply solution. The EVM uses the TPS61175
adjustable output boost converter, external schottky diode, input and output capacitors, inductor, and the
appropriate feedback and compensation components to provide a regulated 24V.
