ISL97649B NOT RECOMMENDED FOR NEW DESIGNS NO RECOMMENDED REPLACEMENT contact our Technical Support Center at 1-888-INTERSIL or www.intersil.com/tsc TFT-LCD Supply + DCP + VCOM Amplifier + Gate Pulse Modulator + RESET DATASHEET FN7927 Rev 2.00 June 27, 2013 The ISL97649B is an integrated power management IC (PMIC) for TFT-LCDs used in notebooks, tablet PCs, and monitors. The device integrates a boost converter for generating AVDD. VON and VOFF are generated by a charge pump driven by the switching node of the boost. The ISL97649B also includes a VON slice circuit, reset function, and a high performance VCOM amplifier with DCP (Digitally Controlled Potentiometer) that is used as a VCOM calibrator. The AVDD boost converter features a 1.5A /0.
