TPS65820RSHT

Overview

The TPS65820RSHT is a power management integrated circuit (PMIC) from Texas Instruments, designed for portable multimedia applications. It integrates multiple DC-DC converters and linear regulators to provide efficient power distribution. The device features a wide input voltage range and supports various output configurations suitable for complex system requirements. It includes protection mechanisms such as over-current and thermal shutdown to ensure reliable operation under diverse load conditions.

Feature Summary

• Integrates high-efficiency synchronous buck converters for core voltage generation
• Includes programmable linear regulators for low-noise analog supply rails
• Supports flexible sequencing and monitoring of multiple power domains

Applications

• Portable media players and smartphones
• Tablet computers and handheld devices
• Digital cameras and camcorders

Procurement Notes

Verify the specific suffix RSHT against the manufacturer's official datasheet to confirm package type, temperature grade, and tape/reel specifications. Ensure compatibility with your PCB footprint and reflow profile requirements. Cross-reference the full part number with authorized distributors to avoid counterfeit components and confirm current production status.

Selection Notes

Select this component when a highly integrated PMIC solution is required for battery-powered multimedia systems. Evaluate the total number of required power rails against the internal converter count to minimize external components. Consider the board space constraints and thermal performance needs, as the integrated design reduces passive component count compared to discrete solutions.

Part Context

This part belongs to the TPS6582x family of PMICs optimized for mobile applications. It shares functional similarities with other TI PMICs but offers a specific combination of converters tailored for display and processor power needs. It serves as a central power hub in systems requiring multiple regulated voltages from a single lithium-ion or lithium-polymer battery source.

Replacement Considerations

Consult the official replacement guide for pin-compatible alternatives within the TPS658xx series. Verify that any substitute part matches the electrical characteristics and control interface requirements of the original design.
