Overview
The LT1944EMS#PBF is a high-efficiency, synchronous step-up DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7V to 4.2V and provides three isolated outputs: +5V at 30mA, +15V at 2.5mA, and -10V at 1mA. The device utilizes a fixed switching frequency architecture to minimize external component count while maintaining regulation across the specified load conditions.
Feature Summary
- Integrates synchronous rectification for improved conversion efficiency
- Provides three independent regulated output rails from a single input source
- Utilizes compact surface-mount packaging for space-constrained designs
Applications
- Portable instrumentation requiring multiple supply rails
- Battery-powered medical devices
- Industrial sensor interfaces
Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm package type and temperature rating. Ensure compatibility with required input voltage ranges and load currents before integration. Cross-reference datasheet revisions to validate pinout consistency and electrical characteristics for the final design implementation.
Selection Notes
Select this component when a single-input solution is required to generate positive and negative auxiliary voltages. Evaluate thermal performance under maximum load conditions. Confirm that the available output current capabilities meet the system requirements for all three rails simultaneously.
Part Context
This part belongs to the LT1944 family of power management ICs designed for low-voltage step-up applications. It serves as a complete power solution for systems needing multiple supplies without complex transformer-based topologies. The device integrates control logic, switches, and inductors into a unified module structure.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Generic equivalents may not match the integrated inductor specifications or isolation requirements.
