Using ADP5520 for driving SHARP LCD backlight

Hi,

 

We are planning to use the ADP5520 Backlight driving chip for our LCD panel - SHARP - LQ043T3DG01. Datasheet can be downloaded from here:

http://www.google.co.in/url?sa=t&rct=j&q=sharp%20lq043t3dg01&source=web&cd=1&ved=0CDAQFjAA&url=http%3A%2F%2Fwww.sharpsme.com%2Fdownload%2FLQ043T3DG01-SPpdf&ei=5caCT6WoCpHMrQfvksHeBQ&usg=AFQjCNE8xPyTp0LW6AXB_0xxWSb0adR61Q&cad=rja

 

Could someone please confirm if ADP5520 can drive the backlight for the above display. The chip datasheet mentions the right voltage range needed but it also says it can support only upto 6 LEDs while this SHARP display has 9 LEDs. Should it make the difference as long as the voltage is within range?

 

Best regards,

Ashish
