LT3693IMSE#TRPBF

Overview

The LT3693IMSE#TRPBF 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 3.5A of output current. The device features an adjustable output voltage starting from 0.79V, with a maximum limit of 30V. It supports a programmable switching frequency between 230kHz and 2.45MHz. The component is housed in a 10-MSOP package with an exposed pad and functions within a junction temperature range of -40°C to 125°C.

Feature Summary

• Integrated synchronous rectification for high efficiency
• Programmable switching frequency capability
• Adjustable output voltage regulation

Applications

• Industrial control systems
• Telecommunications infrastructure
• Portable instrumentation

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the IMSE grade matches required thermal and electrical specifications. Ensure compatibility with the 10-MSOP footprint during PCB layout. Check current availability status as supply may be limited or subject to allocation.

Selection Notes

Select this component for applications requiring high input voltages up to 36V. The 3.5A current rating suits moderate power loads. Consider the 10-MSOP package size for space-constrained designs. Verify that the required output voltage falls within the 0.79V to 30V adjustable range.

Part Context

This part belongs to the LT3693 family of micropower step-down regulators. It shares architectural similarities with other Analog Devices buck converters but offers specific current and voltage characteristics. The MSOP-EP package provides thermal performance advantages over standard plastic packages.
