Part Number: TPS63070

Dear Specialists,

My customer is considering TPS63070 and has a question.

I would be grateful if you could advise.

---

There are several spec about Iq.

I'd like to confirm input battery life.

Which spec should I use ?

In this case, I think spec of `into Vin` should be used, is it correct?

Also spec of ` into vout`, when to use it ?

I appreciate your bgreat help.

Best regards,

Shinichi

Hi Julian,

Thank you for your reply.

I confirmed the application note you suggested.

In customer's case, he needs to know Iin, but datasheet doesn't describe.

Because Iq(Vout) is supplied from Vin.

Are there any reference data about Input Current (Iin) data at no load.

I appreciate your great help.

Best regards,

Shinichi

Shinichi-san,
i only have data with 20uA output load.
In this case the input current ranges from 155uA @ VIN=3.75V to 105uA @ VIN=6V to 170uA @ VIN=16V.
If the output voltage is not needed in no load condition, you could disable the converter by pulling EN to low. In that case the converters input current (shutdown current) is max 26uA.
regards,
Julian
