MP5424
DESCRIPTION
The MP5424 is a plete power management solution that integrates four high-efficiency stepdown 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 (f SW) during continuous conduction mode (CCM) greatly reduces the external inductance and capacitance. Full protection features include under-voltage lockout (UVLO) protection, overcurrent 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 startup/shutdown sequence can also be configured via the MTP and controlled via the I2C bus.
The MP5424 requires a minimal number of external ponents, and is available in a small QFN-26 (3.5mmx4.5mm) package.
