The MP5416-0001 is a complete power management solution that integrates four high-efficiency, step-down, DC/DC converters, five low-dropout regulators, and a flexible logic interface.
A 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. 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 pre-set 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.
The MP5416-0001 requires a minimal number of external components and is available in a space-saving, 28-pin QFN (4mmx4mm) package.

The I2C Software allows you to connect a computer to the EVB Board and I2CBUS Kit. It includes modeling software for verification of the part performance. During bench evaluations, different configurations can be obtained easily through the I2C interface. This allows users to optimize each output for their requirements. All the non-programmed parts need only current and output voltage values to start the evaluation. The other parameters, as defined in the GUI, have default settings that could be modified by the user, if needed.
