LT3587
APPLICATIONS INFORMATION
Lower Input Voltage Applications
The LT3587 can be used in lower input voltage applica-
tions. The V IN supply voltage to the LT3587 must be
2.5V to 6V. However, the inductors can be run off a lower
voltage. This allows the outputs to be powered off two
alkaline cells. Most portable devices and systems have
a 3.3V logic supply voltage which can be used to power
LED DRIVER
the LT3587. The outputs can be driven straight from the
battery, resulting in higher ef?ciency.
Figure 17 shows a typical digital still camera application
with CCD positive and negative supply as well as an LED
driver powered by two AA cells. The battery is connected
to the input inductors and the chip is powered with a 3.3V
logic supply voltage.
