Automotive Regulators

Our unique solutions work with input voltages from 2.8V to 50V for 12V/24V automotive applications, and generate output rails that power microprocessors, transceivers, sensors and displays. We offer cutting edge ASIL-D certified PMICs for safety automotive applications, enabling low FIT-level system designs and small footprint solutions. Single output regulators are available across a range of output current capabilities, and many offer “low Iq” operation to allow keepalive supplies to minimize current drawn from the battery input.
