LT3905EUD#TRPBF

Overview

The LT3905EUD#TRPBF is a boost switching regulator IC manufactured by Analog Devices Inc. It features an adjustable output voltage range starting from 1.248V up to 65V, with a maximum switch current of 350mA. The device operates within an input voltage window of 2.7V to 12V and supports a switching frequency between 1MHz and 2MHz. It is housed in a 16-WFQFN package with exposed pad and functions as a positive, single-output converter. The component is rated for operation across a temperature range of -40°C to 125°C.

Feature Summary

Boost topology designed for step-up DC-DC conversion applications
Adjustable output voltage capability extending up to high voltage levels
Integrated synchronous rectification for improved efficiency

Applications

Battery-powered systems requiring voltage step-up
Industrial control power supplies
Portable electronic devices

Procurement Notes

Verify the specific suffix EUD against official Analog Devices documentation to confirm pinout and thermal pad configuration. Ensure the TRPBF designation matches the required tape and reel packaging format for automated assembly processes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select this component when a compact boost solution is needed for inputs up to 12V. The 350mA switch current limit suits low-to-medium power loads. Consider the 16-QFN package for space-constrained designs. Verify that the required output voltage falls within the 1.248V to 65V adjustable range and that the operating temperature requirements align with the specified industrial grade limits.

Part Context

This part belongs to the LT3905 family of high-efficiency boost regulators from Analog Devices. The series is characterized by its ability to drive high-voltage outputs from lower input sources using a small footprint. The EUD variant specifies the particular package style and temperature rating within this product line, distinguishing it from other pin-compatible or functionally similar regulators in the portfolio.
