4-Channel Integrated LCD Supply  
Features  
The ISL97650B represents a high power, integrated LCD  
supply IC targeted at large panel LCD displays. The  
ISL97650B integrates a high power, 3.2A boost converter for  
• 4.2V to 14V Input Supply  
• A Boost up to 20V, With Integrated 3.2A FET

LOGIC  
The ISL97650B has been designed for ease of layout and  
low BOM cost. Supply sequencing is integrated for both

Peak efficiencies are >90% for both the boost and buck while  
operating from a 4.2V to 14V input supply. The current mode  
buck offers superior line and load regulation. Available in the  
36 Ld TQFN package, the ISL97650B is specified for ambient  
operation over the -40°C to +105°C temperature range.
