Data Sheet
March 22, 2010
FN6748.1
4-Channel Integrated LCD Supply
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
A VDD generation, an integrated V ON charge pump, a V OFF
charge pump driver, V ON slicing circuitry and a buck
regulator with 2A switch for logic generation.
The ISL97650B has been designed for ease of layout and
low BOM cost. Supply sequencing is integrated for both
A VDD -> V OFF -> V ON and A VDD /V OFF -> V ON sequences.
The TFT power sequence uses a separate enable to the
logic buck regulator for maximum flexibility.
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.
