LT3467IDDB

Overview

The LT3467IDDB is a monolithic step-up DC/DC converter manufactured by Analog Devices Inc., housed in an 8-lead DFN package. It integrates a 1.1A power switch and operates from an input voltage range of 2.2V to 16V, delivering a regulated output up to 40V. The device features a fixed 1.3MHz switching frequency and includes integrated soft-start functionality to limit inrush current. It supports shutdown mode with a quiescent supply current of 1.2mA and functions reliably across an industrial temperature range of -40°C to +125°C.

Feature Summary

Integrates a high-efficiency 1.1A power switch for compact boost converter designs
Includes internal soft-start circuitry to manage startup inrush currents
Supports low-power operation via a dedicated shutdown pin

Applications

Single-cell lithium-ion battery powered systems requiring voltage boosting
Portable electronic devices utilizing 3.3V input rails
General-purpose step-up conversion for embedded applications

Procurement Notes

Verify the specific suffix (e.g., TRM vs TRPBF) against official manufacturer documentation to confirm packaging type and RoHS compliance status. Confirm availability as some variants may be discontinued or subject to limited supply constraints. Ensure the selected part matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when a compact solution is needed for boosting single-cell lithium-ion voltages. The fixed 1.3MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1.1A current limit and 40V maximum output rating to ensure compatibility with load requirements and input voltage ranges.

Part Context

This part belongs to the LT3467 family of synchronous boost converters designed for space-constrained portable electronics. It shares architectural similarities with other members like the LT3467A but differs in switching frequency and specific electrical characteristics. The IDDB designation indicates an industrial temperature grade variant within the broader product line.
