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.
