Power Management IC

Power management IC integrates various power components to provide stable and suitable voltage for T-Con, Source Driver-IC, Gate Driver-IC, LED BLU and panel cell used in display panel.

The IC integrates step-up boost converter, step-down buck converter, negative regulated charge pump, LDO, OP-AMP, level shifter and other circuits. All desired output voltage and power sequence can be programmable by I2C interface. In addition, built-in protection functions such as overheat prevention and overcurrent protection prevent damage to parts under abnormal conditions.

  • Power Management IC includes a function of LED BLU Driver-IC.
