The FAN5343 is an asynchronous constant-current LED driver capable of efficiently delivering up to 500mW to a string of six (6) 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 FAN5343 uses a 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, overcurrent, short circuit detection, and thermal shutdown protection. In addition, input under-voltage lockout protection is triggered if the battery voltage is too low. The FAN5343 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.
