DESCRIPTION
The EV8865-Q-00A is used for demonstrating
the performance of MPS’s MP8865. MP8865 is
a highly integrated and high frequency
synchronous step-down switcher with I2C
control interface. It is optimized to support up to
6A load current over an input supply range from
4.5V to 21V with excellent load and line
regulation.
Current-Mode operation provides fast transient
response and eases loop stabilization. The
output voltage level can be controlled, on-the fly
through a 3.4Mbps I2C serial interface. Voltage
range can be adjusted from 0.6V to 1.87V in
10mV steps. Voltage slew rate, switching
frequency and power savings mode are also
selectable through the I2C interface. Fully
protection features includes over current
protection, over voltage protection and over
temperature protection.
MP8865 is available in QFN15 (3mmx3mm)
package.
