The Future of Analog IC Technology MP54 16 2.8V-5.5V, Power Management IC with Four 2A/2.5A/4A/4.5A Buck Converters, 5 LDOs, And Flexible System Settings via I2C and OTP DESCRIPTION The MP5416 is a complete power management solution t hat integrates four high-efficiency, st ep-down, DC/DC converters, five low-dro pout regulators, and a flexible logic i nterface. A constant-on-time (COT) cont rol DC/DC converter provides fast trans ient response. The 1.5MHz default fixed switching frequency during continuous conduction mode (CCM) reduces the exter nal inductor and capacitor values great ly. Full protection features include un dervoltage lockout (UVLO)

, over-current protection (OCP), and the rmal shutdown. The output voltage is ad justable through the I2C bus or pre-set by the one-time programmable (OTP) fun ction. In order to determine the most o ptimal output voltage configurations su pported by this device, refer to applic ation note AN139. The power on/off sequ ence is also programmable by the OTP or can be controlled through the I2C bus online. The MP5416 requires a minimal n umber of external components and is ava ilable in a space-saving, 28-pin QFN (4 mmx4mm) package. By using I2C or OTP, u sers can use the MP5416 to program the buck and LDO output voltages, MODE, cur rent limit of buck1 and buck 3, and the enable function of all the bucks and L DO (ENBUCK/LDO). When using just I2C an d no OTP, the MP5416 allows users to pr ogram current limit of buck 2 and 4, sl ew rate (DVS Slew rate), Discharge (DIS CHG), system enable (SYSEN), and softwa re reset (SFRST). Status and ID2 regist ers can also be read via I2C. Some othe r features, such as AUTOON, Frequency, PWR on delay, RST delay, pushbutton tim e, LDORTC output voltage, OTP version, and I2C slave address can only be progr ammed via OTP. FEATURES  Four High- Efficiency Step-Down Converters o Buck1 : 4.5ADC/DC Converter o Buck2: 2.5A DC/ DC Converter o Buck3: 4A DC/DC Converter o Buck4: 2A
