DESCRIPTION

The MP5424 is a complete power management

solution that integrates four high-efficiency step-

down DC/DC converters, three low-dropout

(LDO) regulators, one load switch, and a flexible

logic interface.

Constant-on-time (COT) control in the DC/DC

converter provides fast transient response. The

1.1MHz default switching frequency (fSW) during

continuous conduction mode (CCM) greatly

reduces

the

external

inductance

and

capacitance. Full protection features include

under-voltage lockout (UVLO) protection, over-

current

protection

(OCP),

over-voltage

protection (OVP), and thermal shutdown.

The output voltage (VOUT) can be adjusted via the

I2C

bus

or

preset

by

the

multiple-time

programmable

(MTP)

interface.

The

start-

up/shutdown sequence can also be configured

via the MTP and controlled via the I2C bus.

The MP5424 requires a minimal number of

external components, and is available in a small

QFN-26 (3.5mmx4.5mm) package.
