LвЂ‰DESIGN FEATURES 1.2A Monolithic Buck Regulator
Shrinks Supply Size and Cost with
Programmable Output Current Limit
by Tom Sheehan Introduction
Power supplies are often overqualified
for their job. This is because power
ICs often specify a current limit that
is more than twice the rated output
current of the device. The power supply
components are sized to handle the
maximum current that the IC can deliver, even if loads are unlikely to draw
that current during normal operation.
The components are bigger and more
expensive than they need to be.
There is, however, an alternative:
set an accurate maximum output current on the supply once the real world
load is known. Accurately setting the
maximum output current reduces the
required current rating of the regulatorвЂ™s power path components, thus
replacing big, expensive components
with smaller, less expensive ones.
A limit on the regulatorвЂ™s maximum output limits the maximum power
dissipation of both the supply and …
