Tool/software:

Hi Team, 

Can you share the efficiency of TPS61178 when Vin=3V, Vout=20V. Iout=0.8A? 

Besides, how do you think the efficiency of TPS61178 in this condition compared with TPS61287 and TPS61377?

    Hi Kailun,

    I use the WEBENCH tool to simulate the efficiency, TPS61178 is around 90%, and TPS61287 is around 89%, for TPS61377, the switching frequency is higher than TPS61178, I don't think the efficiency would be better than TPS61178. So looks like TPS61178 is highest efficiency solution here.

    Regards,
