ISL97649B
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.
The ISL97649B provides a programmable VCOM with I2C
interface. One VCOM amplifier is also integrated in the chip. The
output of VCOM is power-up with voltage at the last programmed
8-bit EEPROM setting.
