Introduction The ASL3417SHN is a three channel buck mode LED driver IC with a Limp-home mode.
It delivers constant average DC current to LEDs independent of the input voltage.
The ASL3417SHN supports up to three output channels.
It means that with one driver IC 1, 2 or 3 LED strings can be driven independently of each other.
It provides a cost effective design solution, s
