LTC1699EMS8-80#TRPBF

Power Management - Specialized Overview

The LTC1699EMS8-80#TRPBF is a precision, digitally programmed resistor divider compliant with Intel 5-bit Mobile VID specifications. It operates within a supply voltage range of 2.7V to 5.5V and consumes 350µA of supply current. The device features a ±0.35% maximum programmable resistor divider accuracy for use with 0.8V referenced DC/DC converters. It includes safeguards against bus conflicts and provides three open-drain outputs (CPU_ON, IO_ON, CLK_ON) plus a global control pin (VRON).

Power Management - Specialized Feature Summary

• Complies with Intel 5-bit Mobile VID specifications for precise voltage programming.
• Stores two distinct divider settings accessible via a 2-wire SMBus serial interface.
• Incorporates built-in safeguards to minimize misprogramming errors caused by bus conflicts.
• Provides dedicated open-drain outputs and a global control pin for simultaneous converter shutdown or soft-start.

Power Management - Specialized Applications

• Intel Pentium III desktop processors
• Mobile processor voltage regulation modules
• Digital power management systems requiring VID compliance

Power Management - Specialized Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm the -80 designation matches the required Intel 5-bit Mobile VID specification rather than Desktop VRM standards. Ensure the MSOP-8 package footprint aligns with the target PCB layout constraints before finalizing procurement orders.

Power Management - Specialized Selection Notes

Select this component specifically for applications requiring Intel 5-bit Mobile VID compliance. The -80 variant differs from -81 and -82 versions which support Desktop VRM standards. Verify that the system utilizes a 0.8V referenced DC/DC converter compatible with the internal divider configuration requirements.

Power Management - Specialized Part Context

This part belongs to the LTC1699 family of specialized power ICs designed as SMBus VID voltage programmers. It serves as a critical interface between digital controllers and analog power supplies in processor voltage regulation architectures.

Power Management - Specialized Replacement Considerations

LTC1699EMS8-80#PBF offers identical electrical characteristics in tube packaging instead of tape-and-reel.
