MP3422 suitability

We are looking for a boost controller with the following specifications
Input: 2 to 4.5V
Output: Fixed 3.3V or 3.3V to 4V
Output current: >3A
Low current shutdown.

The application will be to power a 2G modem periodically from single cell battery

I have looked at the MP3422, is this suitable and are there alternatives products to look at that are in stock?
Many thanks

Hello! If slightly above 3A is the max load current you’ll be expecting, MP3422 is not a suitable part as its switch current limit rating is around 6A. Below are 2 options which may work better, MP3423 and MP3424.
