MFS5600AMMA8ES

Power Management - Specialized Overview

The MFS5600AMMA8ES is an automotive-grade dual DC-DC controller and regulator from the FS5600 series. It integrates a high-voltage buck controller supporting up to 15A with external FETs and a 3A buck regulator with internal FETs. The device operates within a 2.7V to 36V input range, delivering outputs between 1.8V and 8V. It features a switching frequency of 250kHz to 3MHz and achieves 93% efficiency at 3A. Packaged in a 32-HVQFN (5x5) surface-mount format, it supports AEC-Q100 qualification and ASIL B functional safety compliance.
