MPQ4228 integrates a monolithic, stepdown switch-mode converter with a single USB current-limit switch, as well as a Type-C 5V at 3A mode configuration channel for USB ports. It achieves 3A of output current across a wide input supply range, with excellent load and line regulation. The USB switch's output is current-limited. The USB port supports Apple 3A divider mode, DCP schemes for BC1.2, and 1.2V/1.2V mode. The USB port also supports USB Type-C 5V @ 3A DFP mode and Type-A mode (CC1 = 97.6Kohm). Fault condition protections include hiccup current limiting, output overvoltage protection (OVP), DP/DM/CC1/CC2 short to battery protection, and thermal shutdown (TSD). The NTC input monitors the temperature of the external PCB, as well as other components. The MPQ4228 requires a minimal number of readily available, standard external components. The MPQ4228 is available in a QFN-22 package. Applications include USB dedicated charging ports (DCP), USB Type-C DFP port.
