MPQ4228-C - Step-Down Converter

General Description

The MPQ4228-C integrates a monolithic, stepdown 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 achieves 3A of output current across a wide input supply range, with excellent load and line regulation.

Key Features

  • Supports BC1.2 CDP Mode.
  • Supports USB Type-C 5V @ 3A DFP Mode.
  • USB_OUT, DP/DM, CC1/CC2 Pins Short- to-Battery Protection.
  • Wide 4.2V to 36V Continuous Operating Input Range.
  • Passes Apple MFI R33 Certification Test.
  • Passes USB-IF Type-C Certification Test.
  • Selectable Switching Frequency (420kHz and 2.2MHz with Spread Spectrum).
  • Integrated High Bandwidth USB2.0 Data Switch with OVP.
  • Adjustable Line Drop Compensation.
  • Accurate 3.55A and 2.85A USB Cu.

MPQ4228-C 3A, 36V, 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, stepdown 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 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 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 (TSD).
