LTC1699EGN-80#TRPBF

Power Management - Specialized Overview

The LTC1699EGN-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 draws 350µA of supply current. The device features ±0.35% accuracy for programmable resistor dividers, enabling switching between two set voltages via a 2-wire SMBus interface. It is housed in a 16-SSOP package and supports an operating temperature range from -40°C to +85°C.

Power Management - Specialized Feature Summary

• Complies with Intel 5-bit mobile VID specifications for precise voltage regulation
• Utilizes a 2-wire SMBus serial interface for digital programming and control
• Incorporates safeguards against errors caused by bus conflicts during operation

Power Management - Specialized Applications

• Intel Pentium III processor power supplies
• Mobile VRM applications requiring VID compliance
• Systems utilizing DC/DC converters with 0.8V reference inputs

Power Management - Specialized Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging rather than tube packaging when sourcing. Confirm the -80 designation matches the required Intel 5-bit mobile VID specification for the target application. Ensure the SSOP-16 package footprint aligns with the PCB design constraints. Check for RoHS3 compliance status if environmental regulations apply to the manufacturing process.

Power Management - Specialized Selection Notes

Select this component when strict adherence to Intel 5-bit mobile VID standards is required for processor core voltage regulation. The integrated safeguards against bus conflicts make it suitable for noisy environments. Consider the 350µA supply current and 16-SSOP package size for space-constrained designs. Verify compatibility with the specific DC/DC converter's 0.8V reference requirement before implementation.
