The ISL97672B is an integrated 6-channel power LED driver for LCD backlight applications. The ISL97672B is capable of driving LEDs with an input from 4.5V to 26.5V and a maximum output up to 45V.
The ISL97672B employs an adaptive boost switching architecture that allows direct PWM dimming with dimming duty cycle as low as 0.007% at 200Hz or 0.8% at 20kHz. PWM Dimming frequency can be as high as 30kHz.
The ISL97672B employs dynamic headroom control that monitors the highest LED forward voltage string for output regulation to minimize headroom voltage and power loss in a typical multi-string operation. Typical current matching between channels is ±0.7%.
The ISL97672B incorporates extensive protection functions that flag whenever a fault occurs. The protections include string-open and short-circuit detections, OVP, OTP, and an optional output short-circuit protection with external fault disconnect switch.
The ISL97672B is offered in a compact 20 Ld QFN 3x4 package and can operate in ambient temperatures of -40°C to +85°C.
