FAN5341

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 formfactor 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, 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 FAN5341 is available in a very low profile, small formfactor 2mm x 2mm x 0.55mm 6-lead UMLP package that is green and RoHS compliant.
