MPQ4228-C

3A, 36V, Step-Down Converter with USB

Charging Port Supporting CDP and Type-C

5V @ 3A DFP Mode, AEC-Q100 Qualified

DESCRIPTION

FEATURES

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

achieves 3A of output current across a wide

input supply range, with excellent load and line

regulation.



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 Current

Limit

Integrated 20mΩ Low R_DS(ON)USB Switch

145°C Internal Load-Shedding Entry

Temperature

EN Shutdown Discharge Function

Fault Indication for OCP, OVP, and OTP

Frequency Synchronization from 200kHz to

2.2MHz



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.



Hiccup Current Limit for both Buck and USB

OVP for USB Switch

±8kV IEC 61000-4-2 Contact Discharge

ESD Rating for CC1 and CC2 Pins

±8kV IEC 61000-4-2 Contact Discharge

ESD Rating with External Small ESD

Diodes on DP and DM Pins



±15kV IEC 61000-4-2 Air Discharge ESD

Rating for DP, DM, CC1, and CC2 Pins

Available in a QFN-22 (4mmx4mm)

Package with Wettable Flanks

Available in AEC-Q100 Grade 1

APPLICATIONS
