DESCRIPTION

The MP8712 is a high-frequency, synchronous,

rectified, step-down, switch-mode converter.

The MP8712 offers a fully integrated solution

that achieves 12A of continuous and 15A of

peak output current with excellent load and line

regulation over a wide input supply range.

Constant-on-time

(COT)

control

operation

provides fast transient response. An open-drain

power good pin (PG) indicates that the output

voltage is in the nominal range. Full protection

features include over-voltage protection (OVP),

over-current protection (OCP), and thermal

shutdown.

The MP8712 is available in a QFN-14

(3mmx4mm) package.
