We would like to use PTN78020WAH for a vout of 2.5V. In the graphs there is no efficiency curves for 2.5V output (datasheet). Can we have a curve for the range of current at Vin =24V please.

    Caroline:

    The PTN78020W for voltages less than 3.6V , has a maximum input voltage is 10 X Vout.

    The 2.5V maximum input voltage is limited to 25V.

    The average efficiency for 2.5Vout  is 93% of the 3.3V efficiency published data.  All  other  3.3V characteristic data applies to the  2.5V output  voltage.
