LT3467AEDDB

Overview

The LT3467AEDDB is a synchronous step-up DC/DC converter manufactured by Analog Devices Inc. It features an integrated high-efficiency power switch capable of delivering up to 1.1A output current. The device operates with an input voltage range from 2.2V to 16V and supports adjustable output voltages up to 40V. It utilizes a fixed switching frequency of 2.1MHz, which allows for the use of compact external components. The IC includes integrated soft-start functionality to limit inrush current during startup. It is housed in an 8-lead DFN package and is rated for operation over an extended temperature range.

Feature Summary

Integrates a high-voltage power switch with internal soft-start control
Supports boost, flyback, and SEPIC topologies for flexible design
Operates at a high switching frequency to minimize passive component size

Applications

Single-cell lithium-ion battery powered systems
Portable medical devices requiring efficient power conversion
Industrial sensor nodes operating from varying battery levels

Procurement Notes

Verify the specific suffix and tape/reel packaging requirements against the official datasheet before ordering. Confirm that the E-grade industrial rating meets your environmental specifications. Ensure compatibility with your PCB footprint for the DFN package. Cross-reference the manufacturer's latest documentation for any updates on material declarations or compliance status.

Selection Notes

Select this component when a wide input voltage range and high peak current are required in a small form factor. The 2.1MHz frequency is suitable for applications prioritizing board space over absolute maximum efficiency at light loads. Consider thermal management solutions due to the high current capability in a compact package. Verify that the desired output voltage falls within the supported adjustable range.

Part Context

This part belongs to the LT3467 family of switching regulators designed for portable and industrial applications. It complements lower-frequency variants by offering reduced passive component sizes. The A-grade designation typically indicates enhanced performance characteristics compared to standard industrial grades. It serves as a core power management solution for battery-operated equipment.
