LT8631IFE#PBF

Overview

The LT8631IFE#PBF 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 and supports switching frequencies between 100kHz and 1MHz. It utilizes a 20-TSSOP package with an exposed pad for thermal management. The component functions within a junction temperature range of -40°C to +125°C and includes shutdown capabilities.

Feature Summary

Integrates internal synchronous switches for efficient buck conversion
Supports wide input voltage ranges suitable for automotive and industrial applications
Features current mode PWM control architecture

Applications

Automotive power systems
Industrial system power regulation
Telecom supplies (36V to 72V)

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when ordering. Confirm the 20-TSSOP-EP package dimensions match the PCB footprint requirements. Ensure the design accounts for the exposed pad thermal connection for proper heat dissipation during operation at maximum load conditions.

Selection Notes

Select this component for designs requiring high input voltage tolerance up to 100V in a compact surface-mount package. It is appropriate for applications needing adjustable output voltages with synchronous rectification efficiency. Consider the thermal performance characteristics of the TSSOP-EP package when determining heatsinking needs for continuous high-current loads.

Part Context

This part belongs to the LT8631 family of high-voltage, micropower step-down regulators. The series is designed to replace linear regulators in high-voltage applications to improve efficiency. The LT8631IFE#PBF variant specifically denotes the pin-compatible version in the TSSOP-20 package with an exposed pad for enhanced thermal performance.
