SUNNYVALE, CA—July 16, 2009—Maxim Integrated Products (NASDAQ: MXIM) announces the MAX17088, a power-management IC (PMIC) that integrates a boost regulator, a programmable VCOM calibrator with nonvolatile memory, a high-current operational amplifier, and a level-shifting scan driver for notebook LCD panels. Developed using Maxim's proprietary high-voltage BiCMOS process, this device includes all functions required to power the LCD source drivers, gate drivers, and VCOM backplane. Through this high level of integration, the MAX17088 provides a cost-effective power solution for LCD panels in notebooks and monitors.
The boost regulator has a 1.2MHz switching frequency and integrates a 20V, 150mΩ power MOSFET. It delivers output voltages up to 18V from a 1.8V to 5.5V input while achieving > 85% efficiency. The integrated operational amplifier drives the VCOM backplane and features ±150mA short-circuit current with a 40V/µs slew rate. The MAX17088 also integrates a scan driver that drives from -25V to +45V and allows output charge sharing to save power. The 2-wire, I²C-controlled VCOM calibrator provides 7-bit setting accuracy and minimizes connector pin count.
The MAX17088 is available in a 6mm x 6mm, 36-pin TQFN package and is fully specified over the -40°C to +85°C extended temperature range. Prices start at $1.25 (1000-up, FOB USA).
Maxim Integrated Products is a publicly traded company that designs, manufactures, and sells high-performance semiconductor products. The Company reported revenue in excess of $2 billion for fiscal 2008. Maxim was founded over 25 years ago with the mission to deliver innovative analog and mixed-signal engineering solutions that add value to its customers' products. To date, it has developed over 6000 products serving the industrial, communications, consumer, and computing markets. For more information, go to www.maxim-ic.com.
