ISL97650 4-Channel Integrated LCD Supply NOTNORERCEOCMOMMEMNEDNEDDEDFORREPNLEAWCDEEMSEINGTNS DATASHEET FN9198 Rev.4.00 April 17, 2009 4-Channel Integrated LCD Supply The ISL97650 represents a high power, integrated LCD supply IC targeted at large panel LCD displays. The ISL97650 integrates a high power, 2.6A 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 ISL97650 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.
