MPQ4228GRE-AEC1 3A, 36V, Buck Converter with USB Charging Port Supporting DCP and Type-C 5V @ 3A DFP Mode, AEC-Q100 Qualified
The MPQ4228 integrates a monolithic, step-down switch-mode converter with a single USB current-limit switch, as well as a Type-C 5V @ 3A mode configuration channel for USB ports. It can achieve up to 3A of output current (IOUT) across a wide input voltage (VIN) 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 = 97.6kΩ).
Fault condition protections include current limiting with hiccup mode, output over-voltage protection (OVP), DP/DM/CC1/CC2 short to battery protection, and thermal shutdown (TSD).
The negative temperature coefficient (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, and is available in a QFN-22 (4mmx4mm) package.
