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, inp...
