LT1676IN8#PBF

Overview

The LT1676IN8#PBF is a wide input range, high efficiency buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 7.4V to 60V and provides an adjustable output voltage from 1.24V to 51V. The device delivers a switch current of 550mA at a fixed switching frequency of 100kHz. It features a single positive output configuration without synchronous rectification. The component is housed in an 8-pin DIP package and supports junction temperatures from 0°C to 125°C.

Feature Summary

Wide input voltage capability supporting up to 60V for industrial applications
Integrated 550mA power switch for compact design
Fixed 100kHz switching frequency for optimized passive component size
Adjustable output voltage via external resistor network

Applications

Industrial point-of-load regulation
Battery-powered systems requiring wide input tolerance
Distributed power supply architectures
General-purpose step-down conversion

Procurement Notes

Verify the specific suffix 'IN8' indicates the through-hole DIP-8 package variant distinct from surface-mount options. Confirm RoHS compliance status via the manufacturer datasheet. Ensure the ordering part number matches the required pinout and thermal characteristics for your PCB layout. Cross-reference the manufacturer's latest documentation for any obsolescence notices or recommended landing patterns.

Selection Notes

Select this component when a non-synchronous buck topology is acceptable and input voltages exceed standard 36V limits. The 550mA output current suits low-to-medium power loads. Consider the 100kHz frequency trade-off between efficiency and filter size. Verify that the thermal performance of the DIP-8 package meets the application's heat dissipation requirements under maximum load conditions.

Part Context

This part belongs to the LT1676 family of wide-input buck regulators. It shares core architecture with surface-mount variants like the CS8 and IS8 packages but utilizes a dual-in-line form factor. The family is designed for robust operation in noisy industrial environments with high transient immunity.
