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.
