LT3095IUDD#TRPBF

Overview

The LT3095IUDD#TRPBF is a dual-channel low noise bias generator from Analog Devices. It integrates two independent channels, each combining a fixed-frequency peak current-mode switching regulator and a low-noise single-resistor programmable linear regulator. The device accepts an input voltage range of 3V to 20V. Each channel provides a 50mA output from the linear regulator section. The switching regulators support multiple topologies including SEPIC, boost, flyback, and inverting configurations to generate required bias voltages.

Feature Summary

• Dual-channel architecture integrating switching and linear regulation stages
• Low-noise single-resistor programmable linear regulators for clean biasing
• Flexible topology support including SEPIC, boost, flyback, and inverting modes
• Fixed-frequency peak current-mode control for stable operation

Applications

• Generating low noise bias supplies from common input voltages
• Powering sensitive analog front-end circuits requiring clean power rails
• Creating multiple isolated or non-isolated bias voltages from a single source

Procurement Notes

Verify the specific suffix IUDD corresponds to the industrial temperature grade and tape-and-reel packaging configuration required for your assembly process. Confirm that the input voltage range of 3V to 20V aligns with your system's power supply characteristics. Ensure compatibility with the selected switching topology before finalizing procurement.

Selection Notes

Select this component when dual independent bias rails are needed from a single input source. It is suitable for applications requiring both high-efficiency switching conversion and ultra-low noise linear regulation. Consider the thermal performance of the DFN package under maximum load conditions and verify that the 50mA linear output current meets the requirements of the downstream circuitry.

Part Context

The LT3095 belongs to a family of dual-channel bias generators designed for complex power management needs. It combines the efficiency of switching converters with the cleanliness of LDOs. This integration reduces component count and board space compared to using discrete solutions for similar functionality.
