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 AVDD generation, an integrated VON charge pump, a VOFF charge pump driver, VONN 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 AVDD -> VOFF -> VON and AVDD/VOFF -> VON 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.
