DESCRIPTION

The MP8867 is a high-frequency, synchronous,

rectified, step-down, switch-mode converter

output current with excellent load and line

regulation over a wide input supply range.

The reference voltage level is controlled by the

voltage ranging from 0.6V to 1.87V in 10mV

steps. The voltage scaling slew rate, the

switching frequency, enable/sync, and power

interface.

Current-mode

operation

provides

a

fast

transient response and eases loop stabilization.

EN/SYNC

supports

external

clock

synchronization, and an open-drain power good

indicates when the output voltage is in the

nominal range. Full protection features include

over-voltage protection (OVP), hiccup over-

current

protection

(OCP),

and

thermal

shutdown.

The MP8867 requires a minimal number of

readily

available,

standard,

external

components and is available in a QFN-14

(3x4mm) package.
