LвЂ‰DESIGN FEATURES Power Management IC Combines
USB On-The-Go and USB Charging in
Compact Easy-to-Use Solution
The USB interface was originally
designed so that the device providing
power (an вЂњAвЂќ device) would act as the
host and the device receiving power (a
вЂњBвЂќ device) was the peripheral. The A
plug of the USB cable would always
connect to the host device and the B
plug would connect to the peripheral.
The USB On-The-Go (OTG) standard,
however, removes that restriction, so
that the B device can now become a
host and the A device can act as a
peripheral.
In the USB specification, standard
hosts and hubs are limited to providing
500mA to each downstream device,
but if a device is designated as a USB
charger, it can supply up to 1.5A. USB
chargers come in two flavors. A вЂњdedicated chargerвЂќ is a charger that is not
capable of data communication with …

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 …
