Maxim Integrated Products announced the MAX17106, a fully integrated PMIC (power-management IC) that is said to minimize BOM cost and solution size for notebook LCD panels. This device is uniquely equipped with two boost regulators, an LDO, a programmable VCOM calibrator with buffer, three high-speed op amps, a high-voltage level-shifting scan driver, and 18KB of EEPROM. Fabricated using Maxim’s proprietary high-voltage BiCMOS process, the MAX17106 integrates all blocks required to power the LCD source drivers, gate drivers, and VCOM backplane.
One boost regulator has a 1.2MHz switching frequency and integrates a power MOSFET. It delivers output voltages up to 14V from a 2.4 to 5.5V input while achieving > 85% efficiency. A second boost regulator generates the GON voltage.
The LDO can supply a 300mA load and provides a highly accurate output voltage. The integrated op amps drive the VCOM backplane and feature a 150mA short-circuit current with a 45V/microsecond slew rate. The level-shifting scan driver swings from -22V to +38V and can swiftly drive capacitive loads. The MAX17106 includes an I2C controlled VCOM calibrator that provides 7-bit setting accuracy. It also integrates 18kB of EEPROM for setting and controlling the VCOM voltage level.
The MAX17106 is available in a 7 x 7mm, 56-pin TQFN package and operates over the -40 to +85°C extended temperature range. Prices start at $1.65 (1000-up, FOB USA).
