LT3095MPUDD#TRPBF

Overview

The LT3095MPUDD#TRPBF is a dual-output power management IC from Analog Devices, designed to generate two low-noise bias supplies from a common input voltage ranging from 3V to 20V. It integrates a fixed-frequency, peak current-mode SEPIC switching regulator and a low-noise, single-resistor-programmable linear regulator. The device provides a boost converter output capable of up to 950mA and a linear regulator output adjustable from 1V to 20V with a 50mA limit. Operating within a temperature range of -55°C to 125°C, it utilizes a 24-WFQFN (3x5) package.

Feature Summary

• Integrates a SEPIC switching regulator and a programmable linear regulator for dual low-noise bias generation
• Supports wide input voltage range from 3V to 20V
• Features peak current-mode control for the switching channel

Applications

• Data acquisition reference designs requiring stable bias supplies
• Systems needing simultaneous isolated or non-isolated negative and positive rail generation
• Low-noise analog circuit powering applications

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the military grade variant MP corresponds to the required environmental specifications. Ensure the 24-QFN footprint matches the PCB layout guidelines provided in the official datasheet. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a single IC solution is needed to derive multiple regulated voltages from a varying input source. It is suitable for designs requiring both high-efficiency switching regulation and low-noise linear regulation. Consider the thermal performance of the 24-QFN package under maximum load conditions. Verify that the input voltage range covers the minimum and maximum operating requirements of the system.

Part Context

This part belongs to the LT3095 family, which combines switching and linear technologies. It is distinct from the LT3090 series, which focuses on negative linear regulation. The MPUDD designation specifies the military temperature range and package type. It serves as a compact power solution for complex analog systems requiring multiple clean power rails.

Replacement Considerations

LT3095EUDD#TRPBF is a commercial grade equivalent with similar electrical characteristics but different temperature ratings.
