LT3680IDD#TRPBF

Overview

The LT3680IDD#TRPBF is a monolithic synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6V to 36V and delivers up to 3.5A of output current. The device features an adjustable output voltage starting from 0.79V, with a maximum output of 30V. It supports a switch frequency range of 230kHz to 2.45MHz and includes integrated soft-start functionality. The component is housed in a 10-lead DFN package (3mm x 3mm) with an exposed thermal pad, designed for surface-mount installation.

Feature Summary

Integrated high-side N-channel MOSFETs enable efficient synchronous rectification within a compact footprint.
Programmable switching frequency allows optimization for specific efficiency and size requirements.
Built-in soft-start limits inrush current during power-up sequences.

Applications

Industrial automation systems
Distributed power architectures
Point-of-load regulation

Procurement Notes

Verify the complete part number including suffixes such as IDD and TRPBF against official Analog Devices documentation to ensure correct temperature grade and reel packaging specifications. Confirm RoHS compliance status and lead-free markings on the physical component or datasheet before integration into production designs.

Selection Notes

Select this component when a wide input voltage range up to 36V is required alongside moderate current capabilities. The adjustable frequency feature provides flexibility for EMI management. Ensure the application demands a synchronous topology for improved efficiency compared to non-synchronous alternatives in similar voltage ranges.

Part Context

This part belongs to the LT3680 family of synchronous buck regulators from Analog Devices. It shares core architectural similarities with other members like the LT3680EMSE but differs in industrial temperature rating and package variant. The family is designed for applications requiring robust performance across varying load conditions.
