ISL97691IRTZ

2.4V LED Driver with Independent Analog and PWM Dimming Controls of  2 Backlights for 3D Application

LED照明驱动器 4 CH Single Cell Li- Ion Battery Powered

The ISL97691IRTZ 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.

Features ISL97691IRTZ

• 2.4V minimum input voltage, no need for higher voltage supplies
