Application Information
Using the FAN5602 to drive LCD backlighting
The FAN5602 4.5 volt option is ideal for driving the back-
lighting and flash LEDs for any portable device. One
FAN5602 device can supply the roughly 150 mA that are
needed to power both the backlight and the flash LEDs.
Even thought drawing this much current from the FAN5602
will drive the part out of the 3% output regulation, it is not a
problem. The backlight and flash LEDs will still be able to
produce optimal brightness at the reduced regulation. When
building this circuit be sure to use ceramic capacitors with
low ESR. Also all capacitors should be placed as close as
possible to the FAN5602 in the PCB layout. Below is an
example circuit for a backlighting / Flash application.
