ISL97677 Description
The ISL97677 is capable of driving typically 96 pieces of 3.4V/50mA LEDs. The ISL97677 has multiple channels of voltage controlled current sources with typical currents matching to ±0.7%, which pensate for the non-uniformity effect of forward voltages variance in the LED strings. To minimize the voltage headroom and power loss in the typical multi-string operation, the ISL97677.
