LT3976IUDD#PBF

Overview

The LT3976IUDD#PBF is a monolithic buck switching regulator from Analog Devices, designed for high-efficiency DC-to-DC conversion. It supports an input voltage range of 4.3V to 40V and delivers up to 5A of output current. The device features an adjustable switching frequency up to 2MHz and maintains a low quiescent current of 3.3µA during regulation with no load. It utilizes a DFN-16 package and operates within a temperature range of -40°C to +125°C.

Feature Summary

Adjustable switching frequency capability
Low quiescent current design for efficiency
Wide input voltage tolerance

Applications

Industrial control systems
Telecommunications infrastructure
Point-of-load regulation

Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the DFN-16 package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your environmental specifications. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.

Selection Notes

Select this component when a wide input voltage range and high output current are required in a compact form factor. The adjustable frequency allows optimization for external component size versus noise performance. Consider the thermal characteristics of the DFN-16 package for heat dissipation in dense layouts.

Part Context

This part belongs to the LT3976 family of step-down regulators. It shares architectural similarities with other Linear Technology buck converters but offers specific current and voltage ratings tailored for demanding industrial applications. The series emphasizes efficiency and transient response.
