LT3481HDD#PBF

Overview

The LT3481HDD#PBF is a 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 2A of output current. The device integrates a 2.8MHz switching frequency, enabling the use of small external components. It features a low quiescent current of 50µA during operation and drops to 2µA in shutdown mode. The regulator is housed in a thermally enhanced 10-lead DFN package.

Feature Summary

Integrates high-efficiency power switches for compact design
Supports adjustable output voltage via external resistors
Includes thermal shutdown protection for reliability

Applications

Portable instrumentation systems
Industrial control equipment
Battery-powered devices requiring efficient voltage regulation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability before integration. Review datasheet specifications for operating temperature ranges and electrical limits to ensure compatibility with target system requirements.

Selection Notes

Select this component when a wide input voltage range and high current capability are required in a small footprint. The 2.8MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure adequate thermal management due to the power density within the DFN package.

Part Context

This part belongs to the LT348x family of high-voltage step-down regulators from Analog Devices. It shares architectural similarities with the LT3480 but offers a higher switching frequency of 2.8MHz versus 2.4MHz, allowing for reduced passive component size while maintaining similar current handling capabilities.

Replacement Considerations

LT3480IDD#PBF serves as a functional alternative with a slightly lower switching frequency (2.4MHz). LT3681HDD#PBF offers integrated Schottky diode functionality. Verify pinout compatibility and thermal performance when substituting.
