Modifications
The absolute maximum input voltage for the TPS61175 IC and this EVM is 18V. Do not apply more 18V to
this EVM unless R6 is removed or IC damage may occur. However, split-rail circuitry can be added to
allow the power stage voltage to reach higher levels. The TPS61175EVM-588 contains unpopulated pads
for a discrete linear regulator to be included, which can extend the input voltage up to 24V.
