LT1776CN8#PBF

Overview

The LT1776CN8#PBF is a high-efficiency buck switching regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 7.4 V to 40 V and delivers an adjustable output voltage with a maximum switch current of 560 mA. The device features a fixed switching frequency of 200 kHz and a low quiescent current of 25 uA. Packaged in an 8-pin PDIP, it supports through-hole mounting and functions across a temperature range of 0°C to +125°C.

Feature Summary

High efficiency performance optimized for wide input voltage ranges
Integrated shutdown control capability for power management
Robust thermal operation suitable for extended industrial environments

Applications

Industrial systems requiring regulated power from higher voltage rails
Battery-powered equipment utilizing step-down conversion
Embedded control circuits needing efficient voltage regulation

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with required input voltage levels and load current demands before integration. Cross-reference datasheet specifications for thermal management requirements and PCB layout guidelines to maintain optimal regulatory performance.

Selection Notes

Select this component when a robust, through-hole buck converter is needed for inputs up to 40 V. Consider its 560 mA current limit and 200 kHz frequency for applications prioritizing simplicity over ultra-high density. Evaluate thermal dissipation needs given the 125°C rating and PDIP packaging constraints compared to surface-mount alternatives.

Part Context

This part belongs to the LT1776 series of high-efficiency buck regulators designed for versatile power supply applications. It provides a reliable solution for stepping down higher voltages to stable lower levels. The PDIP variant ensures ease of prototyping and maintenance in legacy or space-flexible designs requiring durable through-hole construction.
