TPS61021A: Efficiency Graph

Part Number: TPS61021A

Hi,

I want to use DC/DC converter TPS61021A in my design but i am unable to find some information in the datasheet.

I want to know the efficiency of this Boost converter at 25uA load.

In datasheet efficiency graph has given upto 100uA and from Webench also i am unable to find its efficiency less than 100uA.

Please provide its efficiency graph for 25uA. (Vout=3.3V and Vin=2V to 3V)

  • Hi,

    Here's the effi data you need.:
