TPS57040-Q1: TPS57040-Q1 - Efficiency vs. Load Current @ 3.3V missing

Josef Warta

Part Number: TPS57040-Q1

Hello Team,

do we have also this diagram for 3.3V?

Figure 58 shows Efficiency vs. Load Current for Vout=5.0V. Do we have same for 3.3V?

Many Thanks

Hello Alan,
seems that e2e didn't copy the diagram.
I need Figures 58 from datasheet TPS57040-Q1 page 37.

This diagram plots efficiency vs. output current for 5.0V output with different Vin. We need same diagram for Vout = 3.3V.

Is there something available?

Many Thanks

Josef

Well I guess there is only one curve for 8Vin, not the full set as shown in data sheet graph 58 for the 5V output case.

Probably someone will have to generate the desired data set for 3.3Vout.
