Performance Specification Summary
1-3 Introduction
1.2 Performance Specification Summary
A summary of the TPS54373EVM-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 precharge. The output, J3, is open and no voltage
source is present on J4. Using the precharge circuitry on this EVM requires
careful consideration of line and load conditions for proper operation and may
limit the useful operating range of the TPS54373 device.
