MAX1579ETG+

Overview

The MAX1579ETG+ is a specialized Power Management IC designed for LCD display bias and white LED power supply applications. It integrates multiple regulators within a single package to support TFT-LCD systems. The device operates with an input voltage range of 2.7V to 5.5V. It features a high-efficiency boost converter capable of driving white LEDs, alongside buck converters for core and I/O voltage generation. The component is housed in a 24-pin TQFN-EP (4x4mm) package, suitable for surface-mount assembly.

Feature Summary

• Integrates boost and buck regulators for combined LCD bias and LED drive functions
• Supports efficient power management for TFT-LCD display panels
• Includes thermal pad for enhanced heat dissipation in compact designs

Applications

• TFT-LCD panel power supplies
• White LED backlight drivers
• LCD monitor bias circuits

Procurement Notes

Verify the specific suffix ETG+ against the manufacturer's current datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the 24-TQFN footprint aligns with your PCB layout constraints. Confirm RoHS compliance status through official documentation before finalizing procurement.

Selection Notes

Select this component when a single IC solution is required to manage both LCD bias voltages and white LED backlight currents. It is appropriate for space-constrained portable devices or monitors where board area is limited. Consider the integrated nature of the boost and buck stages to simplify schematic design and reduce external component count.

Part Context

This part belongs to the Maxim Integrated PMIC family focused on display technologies. It addresses the need for consolidated power management in LCD modules by combining multiple regulator functions into one chip. This integration helps reduce system complexity and improves reliability compared to discrete solutions.

Replacement Considerations

Consult Analog Devices official substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully if considering generic equivalents.
