DESCRIPTION

The MP5413 is a complete power management

solution that integrates four high-efficiency, stepdown,

DC/DC converters, two low-dropout

regulators, and two controllable GPO ports.

The constant-on-time (COT) control DC/DC

converter provides fast transient response. The

1.5MHz, default, fixed switching frequency

during continuous conduction mode (CCM)

reduces the external inductor and capacitor

values greatly. Four DC/DC converters work with

90-degree phase-shift mode. Full protection

features include under-voltage lockout (UVLO),

over-current protection (OCP), and thermal

shutdown.

The output voltage is adjustable through the I2C

bus or preset by the one-time programmable

OTP) function. The power-on/-off sequence is

also programmable by the OTP or can be

controlled through the I2C bus online. Two GPO

pins can be used to expand the power rails

needed for different applications.

The MP5413 requires a minimal number of

external components and is available in a spacesaving,

38-pin WLCSP-38 (2.7mmx3.1mm)

package.
