Introduction
1.2 Performance Specification Summary
A summary of the TPS54350EVM-235 performance specifications is provided
in Table 1−2. Specifications are given for an input voltage of 12 V and an output
voltage of 3.3 V unless otherwise specified. The ambient temperature is 25_C
for all measurements, unless otherwise noted. The maximum input voltage for
the TPS54350 is 4.5 V to 20 V. The EVM operates over this range but is
designed and tested for 6-V to 18-V input range (12-V nominal).
