TPS61021A: TPS61021A

Part Number: TPS61021A

Hi,

We are designing a battery operated circuit and the battery is a non rechargeable i.e 2 AA batteries in series. 

My questions are

1.Can we connect the battery voltage directly to the NRF52832 IC (initial battery voltage will be maximum of 3.7V)

2.Is there a better buck-boost or boost IC alternative to  TPS61021ADSGT this part with even lesser quiescent current and with more efficiency.

3.And do you have an alternative switch to TPS22958DGKR part with even more lesser supply current /Quiescent.

Please do suggest the best of best.

Awaiting for your response 

thanks in advance

Chiranjeevi.

    Dear Sir,

    Could you please specify the Vin range and the Vout for the TPS61021A, and what is the load current so that I can choose a right part for you.

    For the other part like NRF52832, please post a new thread for it. The person in that product line can help you.
