Maxim Integrated Products has a power management IC which is notable for its two boost regulators, an LDO, a programmable VCOM calibrator with buffer and three high-speed op amps.

There is also an on-chip a high-voltage level-shifting scan driver and 18kbyte of EEPROM.

The MAX17106 is designed to integrate 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 2.4V to 5.5V input while achieving greater than 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.
