EP5358xUI 600mA PowerSoC
Synchronous Buck Regulator
with Integrated Inductor
Description
The EP5358xUI (x = L or H) is rated for up to
600mA of continuous output current. 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 14mm².
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 V_OUT 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.
