MP8868  
High-Efficiency, 10A, 17V, Synchronous  
Step-Down Converter with I2C Interface  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP8868 is a high-frequency, synchronous,  
rectified, stepdown, switch-mode converter with  
an I2C control interface. Its fully integrated  
solution achieves a 10A output current with  
excellent load and line regulation over a wide  
input-supply range.  
•
•
•
Wide 4.5V-to-17V Operating Input Range  
1% Internal Reference Accuracy  
I2C Programmable Reference Output  
Voltage  
•
Range from 0.6V to 1.87V in 10mV Steps  
with Slew Rate Control  
•

•
I2C Selectable Switching Frequency  
200kHz-2MHz Synchronized External Clock  
OTP, OCP Hiccup Indication Via I2C  
Selectable PSM and Fs Through I2C  
Programmable Soft-Start Time  
The reference voltage level is controlled on-the-  
fly by the I2C serial interface with the reference  
voltage range adjustable from 0.6V to 1.87V in  
10mV steps. In addition, the voltage scaling  
slew rate, the switching frequency, enable, and  
power-save mode are selectable through the  
I2C interface.  
Open-Drain Power Good Indicator  
Small 3x4mm QFN14 Package  
Current-mode operation provides fast transient  
response and eases loop stabilization.  
APPLICATIONS  
•

•
•
SoC and Media Processors  
FPGA-based Systems  
ASIC Supplies  
EN/SYNC  
supports  
external  
clock  
synchronization, and an open-drain power good  
pin indicates when the output voltage is in the  
nominal range. Full protection features include:  
Distributed Power Systems  
All MPS parts are lead-free, halogen free, and adhere to the RoHS  
directive. For MPS green status, please visit MPS website under

•
Over-voltage protection (OVP)  
Hiccup over-current protection (OCP)  
Thermal shutdown  
The MP8868 requires a minimal number of  
readily available, standard, external  
components, and it is available in a QFN-14  
(3x4mm) package.
