High-integrated PMIC with integrated EEPROM for TFT LCD notebook panels

Maxim has introduced the MAX17106, a new high-integrated PMIC (power-management IC) with integrated EEPROM for TFT LCD laptop panel applications.

This MAX17106 device includes a high-performance 18V step-up regulator with integrated switch for the source-driver supply, a 38V step-up regulator with temperature compensation for the TFT gate-on supply (VON), a 300mA low-dropout 2.5V internal linear regulator for the logic supply, three high-speed operational amplifiers, a digitally adjustable VCOM calibration device with nonvolatile memory, two electrically erasable programmable read-only memory (EEPROM) blocks (2Kb extended display identification data (EDID) memory and 16Kb timing controller memory) with separate I²C interfaces, and a high-voltage level-shifting scan driver.

The key features of the MAX17106 PMIC are,

Operating input voltage ranges from 2.4V to 3.6V VDDS
0.2mA VDDS of quiescent current
5mA VIN quiescent current (switching)
3mA AVDD of quiescent current (for Op Amps)
1.2MHz of current-mode step-up regulator
VON temperature-compensated step-up regulator
Rail-to-Rail high-speed operational amplifier
High-voltage drivers with scan logic
Programmable VCOM calibrator
Thermal-overload protection

The VON step-up regulator is a simple minimum off-time, pulse-skipping architecture with a variable peak-current threshold. The output voltage is adjusted according to the voltage on the NTC pins (temperature reading) and two voltage levels set by current sources on the VHI and VLO pins.

Package: 56-Pin, 7mm x 7mm Thin QFN package

Operating temperature range: -40°C to +85°C
Price: Starts at $1.65 for 1k pieces
Availability: Now
