Efficiency
The TPS54x73EVM-225 efficiency peaks at load current of about 1 A to 2 A,
and then decreases as the load current increases towards full load. The
efficiency shown in
Figure 2
2
is for the TPS54673 and the TPS54873 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.
