Tool/software:

Hello,

My customer is looking for a boost solution for handheld device.

Please recommend the most suitable replacement for LT8349 based on the criteria below.

- The input is 1 cell battery

- It would be better if the maximum VOUT is close to 6V

- IOUT should be 6A or more.

- It would be better if the product supports the true shutdown function.

Thank you.

Hi JH,

What's the min voltage will be for the 1 cell battery?

There is no released device that has similar specs/functions with LT8349.

TPS61022 can works with 1 cell battery input to max Vout 5.5V. And it has true shutdown function. But the max Iout is smaller than the requirement, When Vin = 2.5V, Vout = 5V, the max guaranteed Iout is around 3A.

Regards

Lei
