MAX1880EUG+T

Overview

The MAX1880EUG+T is a quad-output switching voltage regulator designed for TFT LCD applications. It integrates four DC-DC converters to generate the specific voltage rails required for display panels, including VGH, VGL, VCI, and VCOM. The device operates within an input voltage range of 2.7V to 5.5V and delivers output currents up to 300mA per channel. It utilizes a fixed-frequency current-mode control architecture to ensure stable regulation under varying load conditions. The component is housed in a 24-pin TSSOP package with exposed pad for enhanced thermal performance.

Feature Summary

• Integrates four independent switching regulators for complete TFT LCD bias generation
• Fixed-frequency operation ensures consistent noise filtering and stability
• Built-in soft-start functionality minimizes inrush current during power-up
• Integrated feedback resistors simplify external component count

Applications

• TFT LCD panel driver circuits
• Mobile phone display modules
• Portable electronic device power management
• LCD monitor backplane supplies

Procurement Notes

Verify the exact suffix 'EUG+T' corresponds to the 24-TSSOP package with tape-and-reel packaging. Confirm RoHS compliance status as indicated by the '+' suffix. Check for obsolescence notices or lifecycle changes from Analog Devices prior to finalizing procurement plans.

Selection Notes

Select this component when a single-chip solution for quad-output LCD biasing is required. Ensure the input voltage range matches the system battery or rail specifications. Verify that the thermal requirements of the application are compatible with the TSSOP package dissipation capabilities.

Part Context

This part belongs to the Maxim Integrated family of power management ICs specifically tailored for portable multimedia devices. It replaces discrete regulator solutions, reducing board space and assembly complexity. The MAX1880 series is engineered to meet the stringent efficiency and noise requirements of modern color display technologies.

Replacement Considerations

Direct substitutes include other quad-output TFT LCD regulators from Analog Devices such as the MAX1881 or MAX1882 series, provided pinout and electrical specifications match. Cross-reference with older generations like the MAX1880 without the suffix if lead-free compliance is not strictly required.
