MP8848  
6A, High-Efficiency, Synchronous,  
Step-Down Switcher with I2C Interface  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP8848 is a highly integrated, high-  
frequency, synchronous, step-down switcher  
with an I2C control interface. The MP8848 can  
support up to 6A of load current over an input  
supply range from 2.7V to 6V with excellent  
load and line regulation.  
2.7V to 6V Input Voltage Range  
Up to 6A Load Current  
Internal 32mHigh-Side and 15mLow-  
Side Power MOSFETs  
I2C-Compatible Interface up to 3.4Mbps  
I2C-Programmable Output Range from 0.6V  
to 1.235V in 5mV Steps  
Constant-frequency hysteretic mode provides  
an extremely fast transient response without  
loop compensation to achieve high efficiency  
easily under light-load condition.  
Factory Adjustable Switching Frequency  
from 0.85MHz to 2.2MHz  
Power-Saving Mode Selectable via I2C  
Internal 1ms Soft Start  
The output voltage level can be controlled on-  
the-fly through a 3.4Mbps I2C serial interface.  
The voltage range can be adjusted from 0.6V to  
1.235V in 5mV steps. The voltage slew rate,  
switching frequency, and power-saving mode  
are also selectable through the I2C interface.  
Power Good Indicator  
Current Overload and Thermal Shutdown  
Protection  
Available in  
Package  
a
QFN-15 (2mmx3mm)  
APPLICATIONS  
Full protection features include internal soft  
start, over-current protection (OCP), and over-  
temperature protection (OTP).
