LT1945IMS#PBF

Overview

The LT1945IMS#PBF is a dual-output switching regulator IC manufactured by Analog Devices Inc. It supports non-inverting, inverting, step-up, and step-down topologies with an input voltage range of 1.2V to 15V. The device provides two adjustable outputs ranging from ±1.23V to 36V/-34V. It features a typical quiescent current of 20µA and operates within a temperature range of -40°C to 85°C. Packaged in a 10-pin MSOP, it delivers up to 250mA switch current.

Feature Summary

Supports multiple DC-DC conversion topologies including boost, buck, inverting, and SEPIC configurations.
Provides independent positive and negative output rails for dual-supply applications.
Features low quiescent current consumption for improved efficiency in battery-powered systems.

Applications

Portable instrumentation requiring dual polarity power supplies
Battery-operated devices needing flexible voltage regulation
Industrial control systems with isolated or split-rail requirements

Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the package type matches the design footprint requirements. Check for any recent Product Change Notifications regarding material declarations or marking changes. Ensure the operating temperature grade meets the environmental specifications of the target application.

Selection Notes

Select this component when dual output generation from a single input is required without external transformers. Consider the 250mA switch current limit for load requirements. Evaluate the need for adjustable outputs versus fixed voltage regulators. Verify compatibility with the available PCB space for the 10-pin MSOP package.

Part Context

This part belongs to the LT1945 family of dual-output DC-DC converters. It is designed to simplify power supply design by integrating two switching regulators into a single compact package. The series targets applications where board space is limited and multiple voltage rails are necessary.
