TPS62624: About Figure 4. TPS6262x and TPS6262xEVM Efficiency

Hi Kanemaru-san,

An aircoil inductor is a newer inductor construction technique which is said to eliminate all switching/core losses. Thus, there are just DCR losses and it is more efficient. It is therefore shown as a reference of how high the efficiency can be, with a perfect (AC) inductor.

What is your Vin, Vout, and Iout required? For example, we have the newer, smaller TPS62801 which generates even higher efficiency than the above with a normal inductor.

Hi Chris-san,

 

Thank you for the information and your advice.

I understand that this data of Aircoil is simulation value so not actual data (not actual parts number).

Is my understanding correct?

Hi Kanemaru-san,

It is measured data with an air coil inductor. Let me check if I can find further details.

What do you need in your application?

Hi Chris-san,

 

Application is consumer device.

Our customer would like to know the parts number of Aircoil.

 

I’d greatly appreciate your verification.

I’m looking forward to hearing from you.
