LT3500IDD#TRPBF

Overview

The LT3500IDD#TRPBF is a monolithic power management IC integrating a 2A synchronous step-down switching regulator and a linear regulator/controller. It operates with an input voltage range of 3V to 36V and delivers up to 2A of output current. The device features a fixed 2.2MHz switching frequency, adjustable output voltage starting from 0.8V, and supports two independent outputs. It is housed in a 12-lead DFN package and rated for operation between -40°C and +150°C.

Feature Summary

• Integrates a high-efficiency synchronous buck converter with a dedicated linear regulator controller on a single die
• Supports wide input voltage ranges suitable for automotive and industrial bus architectures
• Provides precise current limiting and thermal protection for robust system reliability

Applications

• Automotive infotainment and body control modules requiring dual rail generation
• Industrial data acquisition systems needing isolated or non-isolated power rails
• Telecommunications equipment utilizing standard 24V or 48V supply lines

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and thermal pad requirements. Ensure the ordering part number matches the exact tape and reel quantity specified in the manufacturer's latest datasheet revision. Cross-reference the date code and lot information to guarantee component authenticity and traceability.

Selection Notes

Select this component when space-constrained designs require both switched and linear regulation capabilities within a single footprint. Evaluate the thermal performance under maximum load conditions given the compact DFN package. Confirm that the required output voltage range aligns with the internal reference specifications before finalizing the bill of materials.
