Description

The EP5357xUI (x = L or H) is a 600mA

PowerSOC. The EP5357xUI integrates MOSFET

switches,

control,

compensation,

and

the

magnetics in an advanced 2.5mm x 2.25mm

QFN Package.

Integrated magnetics enables a tiny solution

footprint, low output ripple, low part-count, and

high reliability, while maintaining high efficiency.

The complete solution can be implemented in as

little as 10mm2.

A proprietary light load mode (LLM) provides high

efficiency in light load conditions.

The EP5357xUI uses a 3-pin VID to easily select

the output voltage setting.

Output voltage

settings are available in 2 optimized ranges

providing coverage for typical VOUT settings.

The VID pins can be changed on the fly for fast

dynamic voltage scaling. EP5357LUI further has

the option to use an external voltage divider.
