Hi,

I am looking for 12V,2/1.5A constant output.

My input voltage is 10.7V ,which is driven by a 3S1P battery pack.

Can you suggest suitable boost IC for my application.

Can I use LM2623?

Thanks

Kiran

Hi Kiran,

LM2623 doesn't work.

the input voltage could be from 7.5V to 13.5V considering battery SOC. if you want regulate the output to 12V. you would need to find the buck-boost.

Hi Kiran,

I would suggest a buck-boost converter such as TPS55288,

or a sepic topology using LM5155, or LM5157 if the output current is 1.5A.
