Introduction
1.2 Performance Specification Summary
A summary of the TPS54380EVM-225 performance specifications is provided
in Table 1–2. Specifications are given for an input voltage of 3.3 V and an
output voltage of 1.8 V unless otherwise specified. The ambient temperature
is 25°C for all measurements, unless otherwise noted. The data presented in
Table 1–2 compiled with no load on the I/O output. The input voltage range is
limited to 5.5 V by the distribution switch. The maximum input voltage for the
TPS54380 is 6 V.
