Introduction
1.2 Performance Specification Summary
A summary of the TPS54980EVM−022 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 was compiled with no load on the I/O output. The
maximum input voltage for the TPS54980 is 4 V.
