Step-Down/Step-Up Converters

Step-Down/Step-Up Converters

MPS offers a full variety of DC/DC step-down and step-up 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-RDS(ON) FETs, or flexible controllers with external FETs to easily address high current requirements. Our solutions help address common automotive design challenges such as low power density, EMI limits, and solution size limits.

High Efficiency: Low RDS(ON)
Less Design Work: High Integration Simplifies Design
High Flexibility: Flexibly Change the Converter Topology
