I want to know exactly.

What are the efficiencies? when is Input Voltage: 12V and Output Voltage: 1.0V, Current Load: 2.6A?

There are't expressed in datasheet as shown below

If you have any question. Anytime contact me.

The red curves of figures 34 and 35 in the datasheet are for Vin = 12 V and Vout = 1.05 V. The efficiency for 1 V output will be almost identical. You could use Webench to simulate the circuit for 1 V output, but the efficiency difference will be negligible.

You can find the 1.05V output effiecny at Figure 34 and 35, the output is almost same as 1V.

please use it as a reference.

thanks!
