The MAX1517ETJ from Maxim Integrated is a high-performance, step-up converter designed to provide the bias voltages needed for active-matrix, thin-film transistor (TFT) liquid-crystal displays (LCDs). It is particularly suitable for small- to medium-sized panels used in laptop computers, desktop monitors, and portable DVD players.

This advanced power management IC incorporates a high-frequency step-up controller, a positive two-stage charge pump, a negative single-stage charge pump, and a linear regulator. Together, these components generate the required supply voltages for the source driver and gate driver in TFT panels, ensuring crisp and clear display quality.

The MAX1517ETJ operates at a switching frequency of 1.2MHz, which allows for the use of small, low-profile inductors and capacitors, thus minimizing the overall solution footprint. This makes it an ideal choice for space-constrained applications.

Key features of the MAX1517ETJ include:

• Integrated high-efficiency step-up controller
• Positive and negative charge-pump controllers
• Adjustable output voltages for versatile application use
• Low noise and controlled slew-rate outputs to prevent interference with display operation
• Thermal shutdown and overvoltage protection for enhanced safety and reliability
• Small, 32-pin Thin QFN package for a compact design

With its comprehensive protection features, the MAX1517ETJ ensures long-term reliability by safeguarding against conditions that might damage the device or the end application. The built-in thermal shutdown feature prevents overheating, while the overvoltage protection circuitry disconnects the load in case of an output overvoltage condition, thus protecting the TFT panel.

For designers looking for a robust and efficient solution for LCD bias supplies, the MAX1517ETJ from Maxim Integrated offers an excellent blend of performance, integration, and compactness, making it a leading choice in the market.
