The MPQ4487 integrates a monolithic, step-down, switch-mode converter with two USB current-limit switches and Type-C 5V @ 3A mode configuration channels for each port. The MPQ4487 achieves 6A of output current with excellent load and line regulation over a wide input supply range.
The output of each USB switch is current-limited. Both USB ports support USB Type-C 5V @ 3A DFP mode, eliminating the need for outside user interaction.
Full protection features include hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown.
The MPQ4487 requires a minimal number of readily available, standard, external components and is available in a QFN-26 (5mmx5mm) package.
