Chip solution DC-DC chip MP5402MGR

Input voltage: 7-32v

Output voltage: 5V fixed voltage

Output current: 2.7A dual independent current limit can be set (large current requires sufficient heat dissipation)

Switching frequency: 350kHz, 250kHz, 150kHz programmable

Load test output efficiency:

Single channel 1A (92.6%), 2A (91.7%), 2.5A (91.3%),

MPS launches a vehicle-based fully integrated, dual-channel 4.8A, USB charging chip - MP5402M.

A single chip can provide dual 4.8A USB interfaces, and directly use the car battery to identify and quickly charge any portable device.

The single-port and dual-port low-current cigarette lighter car chargers currently on the market cannot meet the demand for high-current charging of tablets and mobile phones at the same time.

While the charging current increases, excessive voltage drop on the USB cable may cause unstable operation of tablets and mobile phones. Intelligent line loss compensation technology is particularly important.

Low-cost car chargers can also introduce noise that interferes with the normal operation of car electronic systems.

The MP5402M launched by MPS solves the above problems very well.

This chip solution integrates all the functions of the traditional three-chip solution:

Low EMI 36V/4.8A step-down DC-DC converter;

Two independent USB current limiting and overvoltage protection switches;

USB charging mode enumerator that can identify any type of portable device.
