Description
The FAN5606 LED driver generates regulated output cur-
rents from a battery with input voltage varying between 2.7V
to 5V. An internal NMOS switch drives an external inductor,
and a Schottky diode delivers the inductor’s stored energy to
the load. Soft start circuitry prevents excessive current drawn
from the supply during power on. Any number of LEDs can
be connected in series as long as the summed forward volt-
ages do not lead to exceeding the specified operating output
voltage range.
In the FAN5606 device, the internal two-bit D/A converters
provide programmability of the output channel current.
Analog programming of the output current is also possible
in the FAN5606. To do this, ground the “B” pin and connect
a resistor between the “A” pin and a fixed supply voltage.
The output current can then be programmed to any desired
value within its specified range. The analog version uses a
single external resistor to set the current, and to turn the
device ON and OFF. The device is available in an 8-lead
MLP package.
