DESCRIPTION
The EV8867-LE-00A is used for demonstrating
the performance of MPS’s MP8867. MP8867 is
a highly integrated and high frequency
synchronous step-down switcher with I2C
control interface. It is optimized to support up to
8A load current over an input supply range from
4.5V to 17V 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 an I
2
C serial interface.
Reference voltage range can be adjusted from
0.6V to 1.87V in 10mV steps. Voltage scaling
slew rate, enable and power saving mode are
also selectable through the I
2
C interface. Full
protection features include over voltage, hiccup
over-current protection and thermal shut down.
The MP8867 is available in QFN-14(3mmx4mm)
package.
