8-Channel LED Driver
The ISL97636 is an integrated power LED driver that
controls 8 channels of LED current for LCD backlight
applications. The ISL97636 is capable of driving typically 72
(8x9) pieces of 3.5V/30mA or 80 (8x10) pieces of
3.2V/20mA LEDs. The ISL97636’s contains 8 channels of
voltage controlled current sources with typical currents
matching of ±1%, which compensate for the non-uniformity
effect of forward voltages variance in the LED stacks. To
minimize the voltage headroom and power loss in the typical
multi-strings operation, the ISL97636 features a dynamic
headroom control that monitors the highest LED forward
voltage string and uses its feedback signal for output
regulation.
The LED brightness can be pulse width modulated with an
applied PWM signal from DC to audio noise free 20kHz.
The ISL97636 features extensive protection functions that
include string open and short circuit detections, OVP, OTP,
thermal shutdown and an optional input overcurrent
protection with master fault disconnect switch.
Available in the 24 Ld 4mmx4mm QFN, the ISL97636
operates from -40°C to +85°C with input voltage ranges from
6V to 24V for high LEDs count applications.
