LT3481EDD#PBF

Overview

The LT3481EDD#PBF is a 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 2A of output current. The device features a fixed internal switching frequency of 2.8MHz and a quiescent current of 50µA. It provides an adjustable output voltage from 0.79V to 20V. The component is housed in a 10-lead DFN package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

Integrates high-side and low-side power switches for efficient synchronous rectification
Includes internal compensation to minimize external component count
Features cycle-by-cycle current limiting and thermal shutdown protection

Applications

Automotive electronics systems
Industrial control equipment
Portable instrumentation

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement channel provides valid traceability for automotive-grade components. Cross-reference the manufacturer part number with the latest datasheet revision to avoid discrepancies in performance parameters or packaging details.

Selection Notes

Select this component when a wide input voltage range up to 36V is required alongside a fixed 2.8MHz switching frequency. It is suitable for designs prioritizing compact footprint due to the integrated power switches and minimal external passive requirements. Consider the thermal performance within the DFN package for high-load applications.

Part Context

This part belongs to the LT348x family of micropower step-down regulators designed for automotive and industrial environments. It shares architectural similarities with the LT3480 but utilizes a higher 2.8MHz switching frequency compared to the LT3480's 2.4MHz setting, allowing for smaller passive components.

Replacement Considerations

LT3480EDD#PBF offers similar functionality but operates at a different switching frequency (2.4MHz). LT3684EDD#PBF provides comparable performance with potentially different quiescent current characteristics.
