LT1949EMS8#PBF

Overview

The LT1949EMS8#PBF is a synchronous step-up/step-down DC-DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 1.7V to 12V and provides an adjustable output voltage from 1.7V to 28V. The device supports a maximum switch current of 1A and utilizes a fixed switching frequency of 600kHz. It is housed in an 8-lead MSOP package and functions as a positive, single-output regulator.

Feature Summary

Supports boost, buck, and SEPIC topologies for flexible voltage conversion
Integrates synchronous rectification for improved efficiency
Operates within a standard commercial temperature range

Applications

Portable battery-powered equipment requiring wide input/output flexibility
Single-cell lithium-ion battery systems
Industrial control modules with varying supply requirements

Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the MSOP-8 physical footprint matches your PCB layout constraints. Ensure the 600kHz switching frequency aligns with your electromagnetic interference (EMI) filtering strategy. Cross-reference the manufacturer's latest datasheet for any recent design or material changes.

Selection Notes

Select this component when application requirements demand both step-up and step-down capabilities from a single integrated circuit. It is suitable for designs where input voltages may fluctuate above or below the desired output level. Consider the 1A current limit and 600kHz frequency when determining external passive component values and thermal management needs.

Part Context

This part belongs to the LT1949 family of power management ICs designed for high-efficiency voltage regulation. It serves as a versatile solution for applications needing a compact footprint and broad operating voltage ranges. The MSOP package allows for space-constrained designs while maintaining robust performance characteristics typical of Analog Devices power solutions.
