Monolithic Power Systems (MPS) MPQ448x Step-Down Converters
Monolithic Power Systems (MPS) MPQ448x Step-Down Converters with switching mode offer a 5V at 3A Type-C configurational channel for the USB port. These step-down converters achieve up to 6A of output current with excellent load and line regulation over a wide input supply range. The MPQ448x converters offer single and dual USB current-limit switch variants with options for programmable frequency and spread spectrum features. These converters control the power of USB ports and also provide support for Dedicated Charging Ports (DCP).These step-down converters provide full protection features that include hiccup current limiting, output over-voltage protection, and thermal shutdown. With a minimal number of external components required and 5mm x 5mm QFN-package, these converters are readily applicable in USB hubs and USB Type-C charging ports.
