MP8774H

12A, Wide-Input 3V to 18V, 1.4MHz

Synchronous Step-Down Converter with PG and

External Soft Start in 3mmx3mm QFN Package

DESCRIPTION

FEATURES

The MP8774H is a fully integrated, high-

frequency, synchronous, rectified, step-down,

switch-mode converter with internal power

MOSFETs. The MP8774H offers a very

compact solution that achieves 12A of

continuous output current with excellent load

and line regulation over a wide input range. The

MP8774H uses synchronous mode operation

for higher efficiency over the output current load

range.



Output Adjustable from 0.6V

Wide 3V to 18V Operating Input Range

12A Output Current

16mΩ/5.5mΩ Low R_DS(ON)Internal Power

MOSFETs

100μA Quiescent Current

High-Efficiency Synchronous Mode

Operation



Pre-Biased Start-Up

Fixed 1.4MHz Switching Frequency

External Programmable Soft-Start Time

Enable (EN) and Power Good (PG) for

Power Sequencing

Constant-on-time (COT) control operation

provides very fast transient response, easy loop

design, and very tight output regulation.



Over-Current Protection and Hiccup Mode

Thermal Shutdown

Available in a QFN-16 (3mmx3mm)

Package

Full protection features include short-circuit

protection (SCP), over-current protection (OCP),

under-voltage protection (UVP), and thermal

shutdown.

The MP8774H requires a minimal number of

readily available, standard external components,

and is available in a space-saving QFN-16

(3mmx3mm) package.

APPLICATIONS



Security Cameras

AP Routers, XDSL Devices

Digital Set-Top Boxes

Flat-Panel Television and Monitors
