TPS65110RGE

Special Purpose Regulators Overview

The TPS65110RGE is a specialized power management integrated circuit designed for Low-Temperature Polycrystalline Silicon (LTPS) LCD bias applications. Manufactured by Texas Instruments, this device functions as a triple charge pump regulator housed in a compact 24-VQFN package with exposed thermal pad. It integrates three independent output channels to provide the necessary voltage rails for LTPS display drivers. The component operates within an input voltage range of 2.7V to 5.8V and supports switching frequencies up to 520kHz. It is rated for industrial operating temperatures ranging from -40°C to 85°C, ensuring reliable performance in demanding electronic environments.

Special Purpose Regulators Feature Summary

• Integrates three independent charge pump outputs specifically optimized for LTPS LCD bias requirements
• Utilizes switched-capacitor regulation architecture to generate negative and positive supply voltages efficiently
• Features a compact 24-pin VQFN package with an exposed pad for enhanced thermal dissipation
• Supports high-frequency operation up to 520kHz to minimize external passive component size

Special Purpose Regulators Applications

• Bias power supply generation for LTPS LCD panels
• Negative voltage rail generation for TFT-LCD gate drivers
• Positive voltage rail generation for source drivers in mobile displays
• Portable electronics requiring efficient multi-rail power for display subsystems

Special Purpose Regulators Procurement Notes

Verify the exact suffix 'RGE' against the manufacturer's current datasheet to confirm pinout and electrical specifications, as variations may exist. Ensure compatibility with RoHS3 standards if required by your assembly process. Confirm that the 24-VQFN footprint matches your PCB layout guidelines, particularly regarding the exposed thermal pad dimensions and solder mask definitions. Cross-reference the specific revision level to ensure no undocumented changes affect system integration.

Special Purpose Regulators Selection Notes

Select this component when designing LTPS LCD systems requiring a single-chip solution for multiple bias voltages. It is suitable for applications where space constraints limit the use of discrete charge pump circuits. Consider the 24-VQFN package for its thermal performance and small form factor. Evaluate the input voltage range against your system's main power rail to ensure stable operation across all load conditions without requiring additional pre-regulation stages.

Special Purpose Regulators Part Context

This part belongs to Texas Instruments' family of special-purpose regulators tailored for display technologies. It complements other devices like the TPS65101 series, which targets different LCD types such as standard TFT. While the TPS65101 focuses on general TFT control, the TPS65110 is specifically engineered for the higher voltage and current demands of LTPS backplanes. This specialization allows for optimized efficiency and reduced component count in advanced mobile display designs.

Special Purpose Regulators Replacement Considerations

Check for the TPS65110RGERG4 variant, which denotes lead-free compliance. Verify functional equivalence with other LTPS bias generators from Texas Instruments or competitors only if pinouts and electrical characteristics match exactly. Do not substitute with non-LTPS specific regulators without validating voltage ranges and current capabilities.
