MPQ4228-Q 3A, 36V, Step-Down Converter with 1-Channel USB Charging Port Supporting QC3.0 and Type-C 5V @ 3A DFP, AEC-Q100 Qualified DESCRIPTION The MPQ4228-Q integrates a monolithic, stepdown, switch-mode converter with a single USB current-limit switch and Type-C 5V @ 3A mode configuration channel for USB port applications. It achieves 3A of output current across a wide input supply range, with excellent load and line regulation. The output of the USB switch is current-limited. The USB port supports Quick Charge 3.0 (QC3.0) mode. It is backwards compatible with DCP schemes for battery charging specification (BC1.2), Apple 3A divider mode, and 1.2V/1.2V mode, without requiring outside user interaction. The USB port also supports USB Type-C 5V @ 3A DFP mode.
