概要

Support is limited to customers who have already adopted these products.

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.
