Description
ISL97678 8-Channel 45V, 50mA LED Driver The ISL97678 is an 8-channel PWM dimming LED driver for LCD backlight applications.The ISL97678 is capable of.
Features
* dynamic headroom control that monitors the highest LED forward voltage string and uses its feedback signal for output regulation. The ISL97678 features PWM dimming up to 30kHz with 0.4%~100% duty cycle and maintains ±1% current matching across all ranges. The PWM dimming frequency can be adjusted beApplications
* The ISL97678 is capable of driving up to 96 pieces of 3.4V/50mA LEDs but larger numbers of LEDs are possible if the LED forward voltage combined is less than 45V. The ISL97678 has 8 channels of voltage controlled current sources with typical currents matching to ±1%, which compensate for the non-unISL97678 Distributors
