DESIGN FEATURESвЂ‰L Charge Li-Ion Batteries Directly
from High Voltage Automotive and
Industrial Supplies Using Standalone
Charger in a 3mm Г— 3mm DFN
by Jay Celani Introduction
Growth of the portable electronics
market is in no small part due to the
continued evolution of battery capacities. For many portable devices,
rechargeable Li-Ion batteries are the
power source of choice because of their
high energy density, light weight, low
internal resistance, and fast charge
times. Charging these batteries safely
and efficiently, however, requires
a relatively sophisticated charging
system.
One additional problem faced by
battery charger designers is how to deal
with relatively high voltage sources,
such as those found in industrial
and automotive applications. In these
environments, system supply voltages exceed the input ranges of most
charger ICs, so a DC/DC step-down …
