Part Number: TPS61021A

What will be the impact on Boost converter TPS61021A if 4V input is provided for 4V output?

If not possible, any other low cost boost converter which can be used instead?

may be a buck-boost converter is more suitable, could you share more detailed info of your application?

Hi, Can you please suggest buck boost part which can supply 2A peak current even the input voltage falls upto 1V.

Hi Mahava,

i am afraid no such buck-boost converter.

i think TPS61021 will run into pass-through mode in your application.which means the output should be a little lower than input voltage. with 2A peak current, the voltage should be around 0.1V under normal temprature. is it acceptable?
