MP8759GD-Z

DESCRIPTION

The MP8759 is a fully integrated, highfrequency, synchronous, rectified, step-down,

switch-mode converter. It offers a very compact

solution that achieves 8A of continuous output

current and 10A peak output current with

excellent load and line regulation over a wide

input supply range.

The MP8759 operates with high efficiency over

a wide output-current load range based on MPS’

proprietary switching loss reduction technique

and internal low RDS(ON) power MOSFETs.

Adaptive constant-on-time (COT) control mode

provides fast transient response and eases loop

stabilization. The DC auto-tune loop provides

good load and line regulation.

Full protection features include over-current limit,

over-voltage protection (OVP), under-voltage

protection (UVP), and thermal shutdown.

The converter requires a minimum number of

external components and is available in a QFN12 (2mmx3mm) package.
