Step-Down Converters

Easy to Use
Leveraging proprietary
DMOS assembly &
packaging technology
Leading Power Density
Reduces space requirements

Less Design Work
High integration
simplifies designs

MPS offers a full variety of Power Management step-down solutions designed to operate directly from a 12V/24V battery or at the point of load. Choose from highly power dense integrated converters with low-Rdson FETs, or flexible controllers with external FETs to easily address high current requirements. Our solutions help address common automotive design challenges like load-dump tolerance, EMI limits, and operation above or below AM band.
