LT1944EMS#TRPBF

Overview

The LT1944EMS#TRPBF is a dual micropower step-up DC/DC converter manufactured by Analog Devices Inc. It integrates two independent boost converters within a single 10-pin MSOP package. Each converter channel features a fixed 350mA current limit and supports an input voltage range from 1.2V to 15V. The output voltage is adjustable, with a minimum regulation set point of 1.23V. The device operates as a positive adjustable regulator, delivering up to 250mA per switch channel. This configuration allows for the generation of multiple stable power rails from a single low-voltage source in space-constrained applications.

Feature Summary

• Dual integrated boost converter architecture providing two independent high-side switching channels
• Micropower design optimized for efficiency in battery-powered and portable electronic systems
• Fixed internal current limiting mechanism ensures protection against overload conditions on each channel

Applications

• Portable handheld devices requiring multiple regulated supply rails
• Battery-operated instrumentation utilizing single-cell or multi-cell power sources
• Embedded systems needing compact dual-output voltage boosting solutions

Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm package integrity upon receipt, as the MSOP form factor requires careful handling during surface-mount assembly. Cross-reference the specific ordering suffix with official Analog Devices documentation to ensure compatibility with required thermal and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel boost topology is required within strict spatial constraints. The 10-pin MSOP package offers a compact footprint suitable for dense PCB layouts. Ensure the application input voltage falls within the specified 1.2V to 15V range and that the load current does not exceed the 350mA internal limit per channel to maintain stable operation and prevent thermal issues.

Part Context

This part belongs to the LT1944 series of switching voltage regulators produced by Analog Devices Inc. The series focuses on micropower step-up conversion technologies designed for efficiency and size reduction. The EMS8 designation indicates the specific MSOP-10 package variant, while the TRPBF suffix denotes the tape-and-reel packaging format intended for automated surface-mount manufacturing processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative dual-channel boost converters from Analog Devices or other manufacturers based on pin compatibility, current limits, and package dimensions if direct substitution is required.
