LT3467AEDDB#TRPBF

Overview

The LT3467AEDDB#TRPBF is a synchronous step-up DC/DC converter manufactured by Analog Devices Inc. It features an integrated power switch capable of delivering up to 1.1A output current with a maximum output voltage of 40V. The device operates within an input voltage range of 2.4V to 16V and supports adjustable output voltages starting from 1.255V. It utilizes a fixed switching frequency of 2.1MHz and includes an integrated soft-start function to limit inrush current. The component is housed in an 8-lead DFN package with exposed pad, designed for surface mount installation.

Feature Summary

Integrates a high-efficiency synchronous rectifier and power switch for compact design
Includes built-in soft-start functionality to manage startup transients
Supports multiple topologies including boost, flyback, and SEPIC configurations

Applications

Single-cell lithium-ion battery powered systems requiring voltage step-up
Portable electronic devices utilizing low-profile power management solutions
General-purpose DC/DC conversion in space-constrained industrial applications

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm that the A-grade designation aligns with required temperature performance specifications. Ensure compatibility with the 8-WFDFN footprint during PCB layout. Cross-reference the manufacturer datasheet for absolute maximum ratings before implementation.

Selection Notes

Select this component when a high-current boost converter is needed with a wide input voltage range. The 2.1MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 1.1A continuous current capability for load requirements. Evaluate thermal performance due to the exposed pad requirement for heat dissipation.

Part Context

This part belongs to the LT3467 family of switching regulators from Analog Devices. It is distinct from the LT3467IDDB variant which operates at a different switching frequency. The LT3467 series is designed for applications requiring efficient power conversion from single-cell sources. It serves as a PMIC solution for portable electronics.
