Hi Team,

Can you recommend a boost?（1.5-1.6Vin, 3.8Vout and current is 1A, peak current may be 2A.）

I think TPS61022 is ok? Or have other better choice?

Hi Amelie,

TPS61022 needs a minimum 1.8V input startup voltage. So it cannot work at 1.5-1.6Vin.

If load current is 1A, TPS61021A would work for this application. But it cannot output 2A current continuously.

May I know where does the input voltage comes from? How long does the peak current last and load current transient speed?
