Step-Down/Step-Up (Buck-Boost) Converters and Controllers

MPS automotive buck-boost converters and controllers offer a variety of power management solutions designed to deliver the regulated output voltage step-down or step-up directly from a 12V/24V battery. Choose from highly power-dense buck-boost converters with integrated, high-efficiency, low-R_DS(ON) FETs or controllers with external FETs. Our automotive buck-boost solutions help address common automotive design challenges such as load-dump tolerance, EMI limits, operation above or below AM band, and optimization system BOM cost.
