MP5408

36V, 6A, Frequency Programmable,

Step-Down Converter with

Smart, Dual, USB Charging Ports

DESCRIPTION

FEATURES



Wide 6V to 36V Operating Input Voltage

Range

The MP5408 integrates a monolithic, step-

down, switch-mode converter with two USB

current-limit switches and charging port

identification circuitry for each port. The

MP5408 achieves 6A of output current with

excellent load and line regulation over a wide

input supply range.



Selectable Output Voltage: 5.1V, 5.17V, and

5.3V



90mV Line Drop Compensation

Accurate USB1/USB2 Output Current Limit

18mΩ/15mΩ Low R_DS(ON)Internal Buck

Power MOSFETs

The output of the USB switch is current-limited.

Both USB ports support DCP schemes for

battery charging specification (BC1.2), divider

mode, 1.2V/1.2V mode, and USB Type-C

5V@3A DFP mode, eliminating the need for

outside user interaction.



13mΩ/13mΩ Low R_DS(ON)Internal

USB1/USB2 Power MOSFETs

Frequency Adjustable (235kHz to 2.2MHz)

Forced Continuous Conduction Mode

(CCM) Operation



Hiccup Current Limit for both Buck and USB

Supports DCP Schemes for BC1.2, Divider

Mode, and 1.2V/1.2V Mode

Full protection features include hiccup current

limiting, output over-voltage protection (OVP),

and thermal shutdown.



Supports USB Type-C 5V @ 3A DFP Mode

±8kV HBM ESD Rating for USB, DP, and

DM Pins

The MP5408 requires a minimal number of

readily

available,

standard,

external

components and is available in a QFN-26

(5mmx5mm) package.
