The ISL97691 is Intersil’s highly integrated 4 channel LED driver
for single cell Li-Ion battery operated mobile displays requiring
analog dimming, and for 3D mobile display applications. It drives
four 40mA channels of LEDs up to 26V from an input supply 2.4V
to 5.5V. The ISL97691 will also drive 60mA channels up to 21V at
30 duty for high peak current 3D modes.
The ISL97691 provides 4 channels of current with 2 independent
analog dimming controls and 2 independent PWM dimming
controls. Channels 1 and 2 form one channel group and channels
3 and 4 form the other channel group. Each channel group’s
analog dimming is controlled through 1-Wire communication
with 6-bit resolution and each channel group’s PWM dimming is
controlled by a separate PWM input. This unique setup allows 2D
or 3D application where independent and dynamic channel
control of LED peak current and PWM dimming duty cycle are
possible. The ISL97691 employs adaptive boost architecture that
allows ultra low dimming duty cycle as low as 0.005 at 100Hz
dimming frequency.
The driver features dynamic headroom control that monitors the
highest LED forward voltage string and uses its feedback signal
for the minimum output regulation.
The ISL97691 incorporates extensive protection functions
including string open and short circuit detections, OVP, and OTP.
The switching frequency can be adjusted from 400kHz to 1.5MHz.
The device is offered in a 16 Ld TQFN 3x3mm package a
