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.
18Ω boost FET with 600/1200kHz switching frequency.
The gate pulse modulator can control gate voltage up to 30V, and both the rate and slew delay time are selectable.
The supply monitor generates a reset signal when the system is powered down.
