TPS61070: Efficiency at VIN=1.8V, VOUT=3.3V, Iout=30mA

Part Number: TPS61070
Other Parts Discussed in Thread: TPS61071,


How much is efficiency at Vin=1.8V, Vout=3.3V, Iout=30mA?

I cannot read from the datasheet.

Best Regards,


  • Hi Kuramochi:

    This graph includes TPS61070 and TPS61071.

    For TPS61070, the efficiency at Vin=1.8V, Vout=3.3V, Iout=30mA is around 85% according to this curve.

    And is the log Axis confused you? Actually, it's similar to the line Axis. Just the grid size is not equal.

    From the left side to right side is :0.01 (...) 0.10 ( ....)  1   (2  3  4  5  6  7  8  9)10 (20  30  40  50  60  70  80  90)100 (.....)1K

    The label inside the () is hidden
