TFT-LCD Supply + DCP + VCOM Amplifier + Gate Pulse Modulator + RESET

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.


FEATUREs
• 2.5V to 5.5V input
• 1.5A, 0.18Ω integrated boost FET
• VON /VOFF supplies generated by charge pumps driven by boost switch node
• 600/1200kHz selectable switching frequency
• Integrated gate pulse modulator
• Reset signal generated by supply monitor
• Integrated VCOM amplifier
• DCP
    - I2C serial interface, address:100111, msb left
    - Wiper position stored in 8-bit nonvolatile memory and recalled on power-up
    - Endurance, 1,000 data changes per bit
• UVLO, UVP, OVP, OCP, and OTP protection
• Pb-free (RoHS compliant)
• 28 Ld 4X5 QFN


APPLICATIONs
• LCD notebook, tablet, and monitor
