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).

The MPQ4228-C requires a minimal number of

readily available, standard external components,

and is available in a QFN-22 (4mmx4mm)

package.
