Hi,
Thank you for utilizing MPS Technical Forum.

MPM3810A is designed for lower output loads, like 1.2A. It is for automotive electronics applications.

The MPM3840 is ideal for powering
portable equipment that run on a single-cell
Lithium-ion battery. It also has external mode control for PFM/PWM.

What is your application and input/output requirement?
