MPQ4228-C-AEC1

36V, 3A, Step-Down Converter with USB Charging Port Supporting CDP and Type-C 5V @ 3A DFP Mode, AEC-Q100 Qualified

Description

The MPQ4228-C 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. The device achieves up to 3A of output current (I_OUT) across a wide 4.2V to 36V input voltage (V_IN) supply range, with excellent load and line regulation.

The USB switch’s output is current-limited. The USB port supports charging downstream port (CDP) schemes and USB Type-C 5V @ 3A DFP mode.

Full protection features include current limiting with hiccup mode, output over-voltage protection (OVP), DP/DM/CC1/CC2 short-to-battery protection, and thermal shutdown.

The MPQ4228-C requires a minimal number of readily available, standard external components, and is available in a QFN-22 (4mmx4mm) package.
