LT8631EFE#TRPBF

Overview

The LT8631EFE#TRPBF is a synchronous micropower step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 100V and delivers up to 1A of output current. The device features adjustable output voltages from 808mV to 60V. Key electrical parameters include a switching frequency of 1MHz, a quiescent current of 16µA, and a shutdown supply current of 3.6µA. It utilizes a TSSOP-EP-20 package and supports operation temperatures from -40°C to +125°C.

Feature Summary

Integrates internal synchronous switches for high-efficiency buck conversion
Supports wide input voltage ranges suitable for automotive and industrial sources
Features low quiescent current for improved efficiency in standby modes

Applications

Automotive systems power regulation
Industrial system power management
Telecom supplies operating between 36V and 72V

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm the manufacturer is Analog Devices Inc. or authorized distributors. Ensure the part matches the TSSOP-EP-20 footprint requirements for your PCB design. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component for designs requiring high input voltage tolerance up to 100V. It is suitable for applications needing a compact solution with integrated synchronous rectification. Consider the 1MHz switching frequency for balancing component size and efficiency. Ensure the thermal performance of the TSSOP-EP-20 package meets the heat dissipation needs of the target load current.

Part Context

This part belongs to the LT8631 series of micropower step-down regulators. The series is designed for applications demanding wide input voltage ranges and high efficiency. The LT8631EFE variant specifically denotes the TSSOP-EP-20 package option within this product line.
