Hi Team,

We have selected TPS61291 chip in boost mode, we required maximum output current is 700mA.

My Setup,

Input Voltage : 2.4V@2500mAh, Output Voltage : 3.3V@700mA.

So does it deliver 700mA output current?

Any help in this case should be appreciated. Waiting for quick response.

Thanks,

Yagnik

no. TPS61291 can't support 700mA output current for 2.4V input. i would suggest TPS61021A for this output power level.

may i know why 1.4~2.4v input voltage, and why the load reach 700mA?
