ISL97678 8 channel LED driver circuit

This 8 channel led driver circuit is designed using the ISL97678 led driver capable of driving up to 96 pieces of 3.4V/50mA LEDs but is possible to drive larger numbers of LEDs if the LED forward voltage combined is less than 45V.
The ISL97678 contains 8 channels of voltage controlled current sources with typical currents matching to ±1%  .

High current LED driver circuit using LT3743

This high current LED driver circuit is designed using LT3743 designed by Linear Technology.
The LT3743 led driver offer high efficiency and require few external components .
