Description

The ACE757Px (x = L or H) is a 1000mA PowerSOC. The ACE757Px integrates MOSFET switches,

control, compensation, and the magnetics in an advanced 3mm x 3mm QFN Package.

Integrated magnetics enables a tiny solution footprint, low output ripple, low part-count, and high reliability,

while maintaining high efficiency.

A proprietary light load mode (LLM) provides high efficiency in light load conditions.

The ACE757Px uses a 3-pin VID to easily select the output voltage setting. Output voltage settings are

The VID pins can be changed on the fly for fast dynamic voltage scaling. ACE757PL further has the

option to use an external voltage

divider.

The ACE757Px offers the optimal combination of very small solution footprint and advanced performance

features.
