Hello Linda-san,

Thank you for your reply.

I have some questions.

1.I think that Rds (on) is the Max value of the TAS5614LA data sheet.

　Is this correct?

2.I did not find DCR from the datasheets and other documents.

　What is this value?

Best Regards,

Hello Hasebe-san,

1. The Rds(on) in the excel file is the max but it would be more accurate to use the typical value to see how much power you can get out of the device.

2. The DCR varies quite a bit depending on the inductor and connector you are using. You can usually find what the DCR of the inductor is from it's datasheet. Same can go for the connector.
