LT3692AEFE#TRPBF

Overview

The LT3692AEFE#TRPBF is a dual current mode PWM step-down DC/DC converter featuring two internal 3.5A switches. It operates with an input voltage range of 3V to 36V and provides adjustable output voltages from 800mV to 34.2V per channel. The device supports a switching frequency of 2.5MHz and delivers up to 3.5A output current. It includes independent shutdown, feedback, soft-start, UVLO, and comparator pins for each channel.

Feature Summary

• Dual-channel architecture with independent control pins for complex power sequencing
• Integrated 3.5A switches for high-density power delivery
• External synchronization capability for noise management
• Dedicated comparator pins for tracking applications

Applications

• Complex power supply tracking requirements
• Output sequencing in multi-rail systems
• High-density point-of-load conversion
• Industrial equipment power management

Procurement Notes

Verify the suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the AEFE grade meets specific temperature or performance criteria required by the design. Cross-reference the manufacturer part number with official Analog Devices documentation to ensure compatibility with existing bill of materials and avoid counterfeit components during procurement.

Selection Notes

Select this component when dual isolated rails require precise tracking or sequential startup without external logic controllers. The independent comparator and feedback pins allow flexible configuration for custom ramp rates. Ensure the application input voltage remains within the 3V to 36V range and that thermal dissipation supports the 3.5A continuous load capability in the chosen enclosure.

Part Context

This part belongs to the LT3692A family of monolithic dual tracking buck regulators. It shares architectural similarities with other high-current synchronous converters but distinguishes itself through dedicated tracking pins. The TSSOP-EP-38 package provides thermal relief for sustained operation. It serves as a compact solution for replacing multiple discrete regulator stages in space-constrained designs.

Replacement Considerations

LT3692AEFE#PBF offers identical electrical specifications but utilizes tube packaging instead of tape and reel. Verify pinout compatibility if substituting between packaging types. No direct functional equivalents exist within the same series; alternative manufacturers require full schematic re-evaluation due to differing control architectures.
