ISL97649B

Features

The ISL97649B is an integrated power management IC (PMIC)

for TFT-LCDs used in notebooks, tablet PCs, and monitors. The

• 2.5V to 5.5V Input

• 1.5A Integrated Boost for Up to 15V A

• 600/1200kHz Selectable Switching Frequency

• Integrated Gate Pulse Modulator

• Reset Signal Generated by Supply Monitor

• Integrated VCOM Amplifier

• DCP

amplifier with DCP (Digitally Controlled Potentiometer) that is

used as a VCOM calibrator.

The A

VDD

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.

- I C Serial Interface, address:100111, MSB Left

- Wiper Position Stored in 8-bit Nonvolatile Memory and

Recalled on Power-up

The ISL97649B provides a programmable VCOM with I C

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.

- 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
