Part Number: TPS61022
Other Parts Discussed in Thread: TPS61021A

Hi,

The customer is considering TPS61022.
Among them, efficiency information is a major criterion.
Do you have efficiency data with the following conditions?

・Vin⁼3.0V
・Vout=3.3V
・Iout=10uA to 0.5A

Yusuke

Hi Yusuke,

the TPS61022 is over-designed for this application, I would suggest TPS61021A. the efficiency data can be found in the datasheet of the TPS61021A

Hi Li,

Thank you for your information.
I introduce TPS61021A together with TPS61022.
However, customers want TPS61022 efficiency information.
Customers believe that the TPS61022 has more margin when it comes to peak currents.
(Peak current is expected to be higher than the required specification.)

Regards,
Yusuke
