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-

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

protection features include over voltage, hiccup

over-current protection and thermal shut down.

The MP8867 is available in QFN-14(3mmx4mm)

package.
