Overview
The TPS65640RHRR is an LCD bias generator with a digital VCOM buffer designed for notebook and tablet PCs. It integrates adjustable sequencing, GPM/GVS control, I2C interface, output discharge, reset generation, and temperature sensing. The device operates from a 2.5V to 5.5V input supply and provides bipolar or unipolar source driver voltages ranging from -8V to 12.7V. Packaged in a WQFN-28 format, it supports display sizes from 7 to 21 inches.
Feature Summary
- Integrates LCD bias generation with a dedicated digital VCOM buffer for display panel stability.
- Includes programmable sequencing and gamma reference management via I2C interface.
- Features built-in temperature compensation and reset generation for system reliability.
Applications
- LCD bias power supplies for notebook computers
- Display driver circuits for tablet PCs
- Monitor LCD bias systems
Procurement Notes
Verify the specific suffix RHRR corresponds to the required tape-and-reel packaging configuration. Confirm that the WQFN-28 package dimensions match the target PCB footprint. Ensure the I2C address settings align with the host controller design. Validate thermal performance requirements for the intended operating environment.
Selection Notes
Select this component when designing power systems for LCD panels requiring integrated VCOM buffering and gamma correction. It is suitable for applications needing compact solutions with minimal external components. Consider the input voltage range and output current capabilities against the specific display panel requirements.
Part Context
This part belongs to Texas Instruments' LCD bias and driver family, specifically targeting portable computing displays. It complements other PMICs by handling specialized analog display needs rather than general-purpose power conversion. The device simplifies board layout by integrating functions typically requiring multiple discrete components.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs before considering alternative devices.
