Power Management IC (PMIC)
MP5408M

MP5408M

6A, 36V, Frequency Programmable Step-Down Converter with Smart, Dual, USB Charging Ports

Active

Datasheet

Description

The MP5408M integrates a monolithic, step-down, switch-mode converter with two USB current-limit switches and charging port identification circuitry for each port. The MP5408M achieves 6A of output current with excellent load and line regulationover a wide input-supply range.
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 modeand USB Type-C 5V@3A DFPmode,eliminating the need for outside user interaction.
Full protection features include hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown.
The MP5408M requires a minimal number of readily available, standard, external componentsand is available in a QFN-26 (5mmx5mm) package.
