LT3467IDDB#TRMPBF

Overview

The LT3467IDDB#TRMPBF is a synchronous step-up DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.2V to 16V and delivers up to 1.1A output current. The device features a fixed switching frequency of 1.3MHz, enabling the use of small external components. It supports adjustable output voltages up to 40V via an external resistor divider. Integrated features include soft-start functionality and shutdown control. The IC is housed in an 8-lead DFN package and is rated for operation between -40°C and +125°C.

Feature Summary

Synchronous rectification architecture for high efficiency
Integrated soft-start limits inrush current
Shutdown pin reduces quiescent current significantly
Fixed 1.3MHz switching frequency minimizes component size

Applications

Battery-powered portable equipment
Single-cell lithium-ion battery boost conversion
General-purpose step-up power supplies
Industrial control systems requiring isolated or boosted rails

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status as manufacturing processes may update over time. Check for obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a compact solution is required for boosting single-cell lithium-ion battery voltages. The 1.3MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure the application requires synchronous rectification for improved efficiency at moderate load currents. Verify that the 16V maximum input voltage aligns with the source supply characteristics.

Part Context

This part belongs to the LT3467 family of high-efficiency synchronous boost converters. It is designed primarily for applications powered by single-cell lithium-ion batteries. The IDDB suffix indicates a specific industrial temperature grade and DFN packaging configuration. It serves as a core power management element in mobile and handheld devices.
