LT3694IFE-1#TRPBF

Overview

The LT3694IFE-1#TRPBF is a monolithic buck regulator with dual low-dropout linear regulators, manufactured by Analog Devices Inc. It operates from an input voltage range of 4 V to 36 V and delivers up to 2.6 A of output current. The switching frequency is adjustable between 250 kHz and 2.5 MHz. The device features a quiescent current of 1 mA and supports an output voltage range from 750 mV to 16 V. It is housed in a TSSOP-EP-20 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-current synchronous buck converter with two independent LDOs for combined power management
• Provides fault-tolerant operation with integrated protection mechanisms
• Supports wide input voltage ranges suitable for industrial and automotive applications

Applications

• Industrial control systems requiring multiple regulated voltage rails
• Automotive electronics operating under varying supply conditions
• Embedded systems needing compact, multi-output power solutions

Procurement Notes

Verify the exact suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official documentation. Check availability as distribution may be limited or subject to allocation. Ensure the TSSOP-EP-20 footprint matches your PCB design requirements before procurement.

Selection Notes

Select this component when a single IC solution is needed for both switching regulation and low-noise linear regulation. The integrated dual LDOs reduce board space compared to discrete solutions. Consider the thermal performance of the exposed pad package for high-load applications. Verify that the adjustable switching frequency meets EMI constraints for your specific design.

Part Context

This part belongs to the LT3694 series of highly integrated power management ICs. It combines a step-down converter with dual LDOs to simplify power architecture. The device is designed for applications requiring efficient conversion alongside clean analog power supplies. It represents a consolidated approach to managing complex power distribution needs in compact form factors.

Replacement Considerations

Check for direct pin-compatible alternatives within the Analog Devices portfolio. Verify if other parts in the LT369x family offer similar integration levels. Ensure any substitute maintains the same input voltage range and output current capabilities.
