LT1945EMS#PBF

Overview

The LT1945EMS#PBF is a dual-output switching regulator IC manufactured by Analog Devices Inc. It operates as a non-inverting, inverting, step-up, or step-down converter with an input voltage range of 1.2V to 15V. The device provides two adjustable outputs ranging from 1.23V to 36V and -34V respectively. Packaged in a 10-pin MSOP, it features a typical quiescent current of 20uA and supports operation temperatures from -40°C to 85°C.

Feature Summary

Dual-output architecture supporting positive and negative rails
Flexible topology including boost, buck, inverting, and SEPIC configurations
Low quiescent current consumption for efficiency optimization

Applications

Automotive electronics requiring dual rail power supplies
Portable devices needing flexible DC-DC conversion topologies
Industrial systems utilizing single battery inputs for multiple voltage levels

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when ordering. Confirm package type matches the 10-pin MSOP requirement. Check RoHS status against project specifications. Ensure temperature grade aligns with extended operating conditions if required. Validate part number authenticity through authorized channels.

Selection Notes

Select this component when dual independent outputs are necessary from a single input source. Consider the wide input voltage range suitable for battery-powered applications. Evaluate the need for both positive and negative output voltages. Assess space constraints regarding the compact MSOP footprint. Verify thermal performance requirements within the specified operating temperature range.

Part Context

This device belongs to the LT1945 family of dual-output DC-DC converters. It shares architectural similarities with other high-efficiency switching regulators but distinguishes itself through its ability to generate simultaneous positive and negative voltages. The series targets applications requiring complex power management solutions in minimal board space.
