Description
The FAN5341 is an asynchronous constant-current LED
driver capable of efficiently delivering up to 500mW to a
string of up to five LEDs in series. Optimized for small form-
factor applications, the 1.2MHz fixed switching frequency
allows the use of small chip inductors and capacitors.
The FAN5341 uses a simple single-wire digital control
interface to program the brightness levels of the LEDs in 32
linear steps by applying digital pulses.
For safety, the device features integrated over-voltage, over-
current,
short-circuit
detection,
and
thermal-shutdown
protection. In addition, input under-voltage lockout protection
is triggered if the battery voltage is too low.
The FAN5341 is available in a very low profile, small form-
factor 2mm x 2mm x 0.55mm 6-lead UMLP package that is
green and RoHS compliant.
