Other Parts Discussed in Thread: TPS8268120

Hi

Customer is searching compact power module.
I would like to recommend TPS8268120.
He is worrying about heat.
Because he is using 12mm*10mm board.

Could you give me Power Dissipation data as the following picture, please?
Customer condition is Vin=5, Vout=1.2, Iout=0.25A


Best regards,
Shimizu

    That is not much power at all, so I see no issue with this little power.

    The power loss is found from the efficiency graphs. Output power divided by the efficiency is input power. The difference is the loss. I get 75 mW loss for your conditions.
