DESCRIPTION
The EV8846-Q-00A is used for demonstrating
the performance of MPS’s MP8846. MP8846 is
a highly integrated and high frequency
synchronous step-down switcher with I
2
C
control interface. It is optimized to support up to
6A load current over an input supply range from
4.5V to 8V with excellent load and line
regulation.
Current-Mode operation provides fast transient
response and eases loop stabilization. The
reference voltage level can be controlled, on-
the fly through a 3.4Mbps I
2
C serial interface.
The voltage range can be adjusted from 0.6V to
1.87V in 10mV steps. The voltage slew rate,
switching frequency and power savings mode
are also selectable through the I
2
C interface.
Fully protection features includes over current
protection, over voltage protection and over
temperature protection.
MP8846 is available in QFN15 (3mmx3mm)
package.
