ISL97650B 4-Channel Integrated LCD Supply RECOMMOEBNSDOELIDSELRT9EE86PP0LR2AOCDEUMCETNT PART DATASHEET FN6748 Rev 1.00 March 22, 2010 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, VON 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.
