One boost regulator has a 1.2MHz switching frequency and integrates a power MOSFET. It delivers output voltages up to 14V from a 2.4V 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 7mm x 7mm, 56-pin TQFN package and operates over the -40 degrees Celsius to +85 degrees Celsius extended temperature range.
