LT3489EMS8E#PBF

Overview

The LT3489EMS8E#PBF is a high-efficiency synchronous boost DC-to-DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.6V to 16V and provides a regulated output voltage adjustable from 2.6V up to 40V. The device supports a continuous output current of 2.5A and integrates a 2.2MHz switching frequency for compact passive component selection. Packaged in an 8-pin MSOP with exposed pad, it is designed for applications requiring efficient step-up conversion within a small footprint.

Feature Summary

Integrates a synchronous power switch for enhanced conversion efficiency
Supports wide input voltage ranges suitable for single-cell lithium battery operation
Features a fixed 2.2MHz switching frequency to minimize external component size

Applications

Portable devices powered by single-cell lithium-ion or lithium-polymer batteries
General-purpose step-up power supplies for embedded systems
Battery-operated equipment requiring stable higher voltage rails

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the MSOP-8 package variant matches your PCB footprint requirements. Ensure the supplier provides official documentation to validate the part number authenticity against Analog Devices specifications before finalizing procurement.

Selection Notes

Select this component when a single-output boost topology is required with an input voltage up to 16V. It is appropriate for designs needing a 2.5A output capability without external pass transistors. Consider the 2.2MHz frequency trade-off between component size and electromagnetic interference levels relative to other family members.

Part Context

This part belongs to the LT3489 series of synchronous boost converters. It shares the core architecture with variants differing in thermal performance or package type, such as the LT3489HMS8E. The EMS8E designation specifically identifies the standard temperature grade version housed in the MSOP-8 package.
