The MAX17105ETG+ from Maxim Integrated is a highly integrated power-supply solution specifically designed to cater to the needs of thin-film transistor (TFT) liquid-crystal displays (LCDs) used in notebook computers. This advanced power management integrated circuit (PMIC) combines a boost regulator, two linear regulators, a high-frequency operational amplifier, and a logic-controlled, level-shifting scan driver in a compact 24-pin thin QFN package.
Key Features
- High Efficiency: The device includes a high-efficiency step-up regulator that is optimized for driving the white LEDs used in backlighting the display, ensuring extended battery life and reduced heat generation.
- Multiple Outputs: It provides multiple regulated outputs, including positive and negative charges for the TFT gate-on and gate-off supplies, making it a versatile solution for various display configurations.
- Integrated Operational Amplifier: With an onboard op-amp, the MAX17105ETG+ can drive the VCOM backplane of the LCD, which is essential for maintaining image quality and stability.
- Level-Shifting Scan Driver: The integrated level-shifting scan driver is designed to interface with low-voltage logic inputs while driving higher voltage LCD panel gate lines, simplifying the design and reducing component count.
- Compact Design: Its small 24-pin TQFN (4mm x 4mm) package makes it an excellent choice for space-constrained applications.
