5V PMIC with High-Efficiency 4.5A/4A/2.5A/2A Four Step-Down Converters, Five LDOs with I2C and OTP

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.
