Hi Yoshimura,

May I check that whether customer want to set TPS61094 to work in Boost Converter with Bypass? Do they not need to charge one back sup cap?

Best Regards,

No, Customer need buck/Boost function.

Customer do not need to charge one back sup cap.

Battery is non-re-chargeable coin battery. then

Hi Yoshimura,

Sorry that I am still confused about customer's application. TPS61094 is used to charge one back up power and supply system power from one continuous input supply. If they don't need back up with non-re-chargeable battery, which type buck/Boost function do they need?

Best Regards,

Customer prefer to use just buckboost function

Hi Yoshimura,

As I said before, TPS61094 is not a typical buck-boost converter. It can only pass through input to output or boost sup cap voltage to output.

For customer's application, the output voltage is changed by battery voltage and cannot be controlled to a stable 3V. Is customer finding one pure buck-boost converter can realize Vin=2.5-3.6V, Vout=3V?

Best Regards,

Eric Yue
