LT3467EDDB#TRMPBF

Overview

The LT3467EDDB#TRMPBF is a monolithic step-up DC/DC converter manufactured by Analog Devices Inc. It operates within an input voltage range of 2.6V to 4.2V, making it suitable for single-cell lithium-ion battery applications. The device delivers up to 1.1A of output current and supports adjustable output voltages from 1.255V to 40V. It features a fixed switching frequency of 1.3MHz and includes integrated soft-start functionality. The component functions in boost topology with a maximum operating junction temperature of 125°C and a minimum of -40°C.

Feature Summary

Integrates a high-efficiency power switch capable of delivering 1.1A continuous current
Includes built-in soft-start circuitry to limit inrush current during startup
Supports flexible output voltage configuration via external feedback resistors
Operates at a fixed 1.3MHz switching frequency for compact passive design

Applications

Single-cell lithium-ion battery powered portable electronics
General purpose step-up power supplies for low-voltage systems
Battery-operated devices requiring regulated higher voltage rails

Procurement Notes

Verify the specific suffix TRMPBF indicates tape and reel packaging with lead-free finish. Confirm the EDDB designation corresponds to the DFN-8 package variant. Check manufacturer lifecycle status as some variants may be discontinued. Ensure compatibility with required thermal dissipation for the selected application environment.

Selection Notes

Select this component when input voltage is limited to a single cell range of 2.6V to 4.2V. Choose based on the need for a 1.1A current capability in a small footprint. Consider the 1.3MHz frequency for balancing size and efficiency. Verify that the DFN-8 package meets board space constraints.

Part Context

This part belongs to the LT3467 series of step-up converters designed for battery-powered applications. It shares architectural similarities with other Analog Devices PMICs but is distinct in its specific input voltage window and current rating. The series focuses on simplicity and reliability for consumer electronics.
