TPS65141RGER

Power Management - Specialized Overview

The TPS65141RGER is a specialized LCD driver IC from Texas Instruments, designed for portable display applications. It integrates four charge pumps to generate multiple voltage rails required for TFT and segment LCDs. The device operates with an input voltage range of 2.7 V to 5.8 V. It features a 5 V/1.6 A I/O supply and adjustable output voltages ranging from 5 V to 15 V. Packaged in a 24-pin HTSSOP with an exposed pad, it supports surface-mount installation and functions within a temperature range of -40 °C to +85 °C.

Power Management - Specialized Feature Summary

• Integrates four independent charge pumps for generating positive and negative LCD bias voltages
• Provides a dedicated high-current 5 V/1.6 A I/O supply rail for display interface logic
• Supports adjustable output voltage configuration via external resistors
• Optimized for low component count in space-constrained portable designs

Power Management - Specialized Applications

• TFT LCD panel bias generation
• Segment LCD driver power supplies
• Portable electronic device displays
• Handheld instrument interfaces

Power Management - Specialized Procurement Notes

Verify the package designation matches the HTSSOP-24 requirement for your PCB footprint. Confirm that the operating temperature range of -40 °C to +85 °C aligns with your environmental specifications. Ensure input voltage constraints between 2.7 V and 5.8 V are respected during system design. Check for moisture sensitivity levels if reflow soldering is planned.

Power Management - Specialized Selection Notes

Select this component when a single-chip solution for multi-rail LCD biasing is required. It is suitable for designs needing a robust 1.6 A I/O supply alongside adjustable charge pump outputs. Consider alternative packages like PWPR if HTSSOP-24 is unavailable or if thermal performance requirements differ. Validate that the 5.8 V maximum input voltage accommodates your system's supply variations.

Power Management - Specialized Part Context

The TPS65141 belongs to Texas Instruments' family of LCD drivers, which also includes variants like the TPS65131 and TPS65145. Unlike the TPS65131, which focuses on dual-output boost/buck-boost regulation, the TPS65141 specializes in multi-channel charge pump generation for complex display panels. It shares functional similarities with the TPS65141PWPR but differs in package type.

Power Management - Specialized Replacement Considerations

The TPS65141PWPR is a pin-compatible alternative offering the same electrical characteristics in a different package format.
