TPS65167RHAR

Power Management - Specialized Overview

The TPS65167RHAR is a compact LCD bias supply integrated circuit designed for TFT-LCD TV panels. It integrates four independent converters to generate required voltage rails, including a 12V/3.5A I/O output and three additional channels for panel biasing. The device operates from a single input supply ranging from 6V to 14V. It utilizes a 40-pin VFQFN package with an exposed pad for thermal management. This PMIC consolidates multiple power stages into a single solution to reduce board space and simplify design for display applications.

Power Management - Specialized Feature Summary

• Integrates four independent switching converters within a single compact package
• Provides high-current 12V output suitable for I/O interface requirements
• Supports flexible configuration for various TFT-LCD panel bias voltages
• Includes built-in protection mechanisms for reliable operation

Power Management - Specialized Applications

• TFT-LCD TV panels
• LCD monitor displays
• Professional display systems requiring multi-rail bias supplies

Power Management - Specialized Procurement Notes

Verify the exact suffix RHAR against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering part number matches the specific tape-and-reel or cut-tape packaging requirements of your assembly line. Cross-reference the revision level to avoid discrepancies in electrical characteristics or thermal performance specifications.

Power Management - Specialized Selection Notes

Select this component when designing for TFT-LCD TVs requiring a consolidated power solution. It is appropriate for systems needing a high-current 12V rail alongside lower voltage bias outputs. Consider the 40-pin VFQFN package constraints for thermal dissipation and PCB layout. Evaluate if the integrated converter count meets the specific voltage requirements of the target display panel without external components.

Power Management - Specialized Part Context

This part belongs to the Texas Instruments TPS6516x family of LCD bias supplies. It shares functional similarities with the TPS65166 but offers distinct channel configurations. The series is engineered specifically for flat-panel display applications, replacing discrete regulator solutions with a unified IC approach to improve efficiency and reduce component count in television and monitor designs.

Power Management - Specialized Replacement Considerations

Check for direct substitutes within the TPS6516x family, such as the TPS65166, ensuring pin-to-pin compatibility and matching electrical specifications. Verify that any alternative component supports the same input voltage range and output current capabilities required by the specific LCD panel design.
