ISL97678 Overview
Key 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 between 100Hz and 30kHz
- The boost switching frequency can also be adjusted between 600kHz and 1.5MHz
