LTC1706CS8-19#TRPBF

Power Supply Controllers, Monitors Overview

The LTC1706CS8-19#TRPBF is a precision, digitally programmable resistive ladder designed to adjust the output voltage of regulators with a 1.19V reference. It operates within an input voltage range of 2.7 V to 5.5 V and delivers a maximum output voltage of 1.825 V. The device features a low operating supply current of 100 nA and draws only 1 uA of input current. It supports VID programming for Intel VRM 8.5 standards and functions reliably across a temperature range of -40°C to +85°C.

Power Supply Controllers, Monitors Feature Summary

• Digitally programmable resistive ladder architecture for precise voltage adjustment
• Compatible with any regulator utilizing a 1.19V internal reference
• Ultra-low power consumption with 100 nA operating supply current
• Supports VID programming protocols for Intel VRM 8.5 specifications

Power Supply Controllers, Monitors Applications

• Intel VRM 8.5 compliant processor voltage regulation modules
• Precision digital adjustment of 1.19V referenced linear or switching regulators
• Low-power embedded systems requiring programmable core voltages

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm compatibility with the target regulator's 1.19V reference requirement. Check for RoHS compliance documentation. Ensure the SOIC-8 narrow package fits the PCB footprint. Validate that the -40°C to +85°C industrial temperature range meets system environmental requirements.

Power Supply Controllers, Monitors Selection Notes

Select this component when a fixed resistor network is insufficient for dynamic voltage scaling. It is suitable for designs requiring precise, digitally controlled adjustments to 1.19V referenced supplies. Consider the 100 nA quiescent current for battery-sensitive applications. Ensure the host controller can interface with the VID pins according to Intel VRM 8.5 timing specifications.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC1706 series of specialized PMICs from Analog Devices. It serves as a bridge between digital control logic and analog voltage regulation. Unlike standard voltage regulators, it acts as a programmable divider, allowing external regulators to be tuned via digital inputs rather than analog potentiometers.
