MP5416
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
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MP5416 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.
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 DC/DC Converter
o 2.8V to 5.5V Operating Input Range
o Adjustable Switching Frequency
o Programmable Forced PWM, Auto
PFM/PWM Mode
o Hiccup Over-Current Protection (OCP)
Five Low-Dropout Regulators
o One RTC Dedicate LDO
o Four Low Noise LDOs
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. In order to determine the most
optimal output voltage configurations supported
by this device, refer to application note AN139.
The power on/off sequence is also
programmable by the OTP or can be controlled
through the I2C bus online.
o Two Separate Input Power Supplies
o 100mV Dropout at 300mA Load
System
o I2C Bus and OTP
o Power-On/-Off Button
o Power-On Reset Output
o Flexible Power-On/-Off Sequence via
OTP
o Flexible DC/DC, LDO On/Off via OTP
o ±4kVHBM and ±2kV CDM ESD Rating
For All Pins
The MP5416 requires a minimal number of
external components and is available in a
space-saving,
package.

APPLICATIONS
By using I2C or OTP, users can use the
MP5416 to program the buck and LDO output
voltages, MODE, current limit of buck1 and
buck 3, and the enable function of all the bucks
and LDO (ENBUCK/LDO).
Cable Modems, Set-Top Boxes
Televisions
MID, Tablets
POS Machines
SSD
IP Cameras
When using just I2C and no OTP, the MP5416
allows users to program current limit of buck 2
and 4, slew rate (DVS Slew rate), Discharge
(DISCHG), system enable (SYSEN), and
software reset (SFRST). Status and ID2
registers can also be read via I2C.
All MPS parts are lead-free, halogen-free, and adhere to the RoHS
directive. For MPS green status, please visit the MPS website under Quality
Assurance. “MPS” and “The Future of Analog IC Technology” are registered

Some other features, such as AUTOON,
Frequency, PWR on delay, RST delay,
pushbutton time, LDORTC output voltage, OTP
version, and I2C slave address can only be
programmed via OTP.
