Efficiency
The TPS54373EVM-237 efficiency peaks at load current of about 1 A to 2 A,
and then decreases as the load current increases towards full load. Figure 2–2
shows the efficiency for the TPS54373 at an ambient temperature of 25
°
C. The
efficiency is lower at higher ambient temperatures, due to temperature
variation in the drain-to-source resistance of the MOSFETs. The efficiency is
slightly lower at 700 kHz than at lower switching frequencies, due to the gate
and switching losses in the MOSFETs.
