MPQ4228-C-AEC1

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

Datasheet

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. It can achieve up to 3A of output current (I_OUT) across a wide input voltage (V_IN) range, with excellent load and line regulation.

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

Fault condition protections include hiccup current limiting, 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.

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 (I_OUT) across a wide input voltage (V_IN) 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.
