DESCRIPTION
The EV8869W-L-00A is used for demonstrating
the performance of MPS’s MP8869W.
MP8869W is a highly integrated and high
frequency synchronous step-down switcher with
I
2
C control interface. It is optimized to support
up to 12A continuous/15A peak output current
over an input supply range from 3V to 18V with
excellent load and line regulation.
COT control operation provides fast transient
response and eases loop stabilization. In I
2
C
control loop, the output voltage level can be
controlled, on-the fly through an I
2
C serial
interface. Output voltage range can be adjusted
from 0.6V to 1.55V in 7.5mV 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, over-current protection and thermal
shut down.
The MP8869W is available in QFN-
14(3mmx4mm) package.
