Description

The EP5358xUI (x = L or H) is a 500mA

PowerSOC. The EP5358xUI integrates MOSFET

switches,

control,

compensation,

and

the

magnetics in an advanced 2.5mm x 2.25mm

micro-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 15mm2.

The EP5358xUI 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. EP5358LUI further has

the option to use an external voltage divider.

The EP5358xUI is a perfect solution for noise

sensitive and space constrained applications that

require high efficiency.
