MP5415GR-0001-P

The MP5415 is a complete power management IC (PMIC) that integrates four high-efficiency, step-down DC/DC converters; five low-dropout (LDO) regulators; and a flexible logic interface. Constant-on-time (COT) control provides fast transient response for the DC/DC converter. The default fixed switching frequency (fSW) (2MHz) during continuous conduction mode (CCM) greatly reduces the external inductor and capacitor values. Full protection features include under-voltage lockout (UVLO) protection, over-current protection (OCP), and thermal shutdown. The output voltage (VOUT) is adjustable via the I2C bus or preset via the one-time programmable (OTP) memory. The start up/shutdown sequence is also configurable via the OTP, or can be controlled via the I2C bus. The buck and LDO output voltages, MODE pin configuration, buck 1 and buck 3 current limits, and the buck and LDO enable functions (ENBUCK/LDO) can be configured via the I2C and OTP. The buck 2 and buck 4 current limits, DVS slew rate, discharge function (DISCHG), system enable function (SYSEN), and the software reset function (SFRST) can be configured via the I2C. The status and ID2 registers can also be read via the I2C. Other parameters such as AUTOON, frequency, PWR on delay, RST delay, pushbutton time, LDORTC VOUT, OTP version, and I2C slave address can only be configured via the OTP. The MP5415 requires a minimal number of external components, and is available in a space-saving QFN-28 (4mmx4mm) package.
