ISL97649A
The ISL97649A 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 A VDD , an LDO for
VLOGIC. VON and VOFF are generated by a charge pump driven by
the switch node of the boost. The ISL97649A also includes a V ON
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/0.18 Ω boost FET with
600/1200kHz switching frequency.
The logic LDO includes a 350mA FET for driving the low voltage
needed by external digital circuitry.
The gate pulse modulator can control the gate voltage up to 30V,
and both the rate and slew delay times are selectable.
The supply monitor generates a reset signal when the system is
powered down.
It provides a programmable VCOM with I 2 C interface. One VCOM
amplifier is also integrated in the chip. The output of the VCOM is
powered up with the voltage at the last programmed 8-bit
EEPROM setting.
