LED Driver, Series Boost, with Integrated Schottky Diode and Single-Wire Digital Interface FAN5341 Description The FAN5341 is an asynchronous constant−current LED driver capable of efficiently delivering up to 500 mW to a string of up to five LEDs in series. Optimized for small form−factor applications, the 1.2 MHz 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.
