LT3692IUH#TRPBF

Overview

The LT3692IUH#TRPBF is a high-efficiency, synchronous step-down DC/DC converter from Analog Devices. It integrates two N-channel power switches and operates with an input voltage range of 2.7V to 18V. The device supports adjustable output voltages down to 0.6V via an external resistor divider. It features a fixed 2MHz switching frequency to minimize passive component size. The controller offers cycle-by-cycle current limiting, thermal regulation, and soft-start capabilities for reliable operation in space-constrained applications.

Feature Summary

• Integrated synchronous rectification architecture for enhanced efficiency
• Fixed high-frequency switching operation reduces external component footprint
• Built-in protection mechanisms including thermal shutdown and current limit

Applications

• Portable instrumentation systems
• Industrial control modules
• Communication infrastructure equipment

Procurement Notes

Verify the complete part number against official Analog Devices documentation to ensure correct suffixes and package type. Confirm that the TRPBF designation indicates tape-and-reel packaging suitable for automated assembly processes. Cross-reference the specific revision level if critical compatibility is required for existing designs.

Selection Notes

Select this component when designing compact power supplies requiring high efficiency within a limited board area. The fixed 2MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Ensure the input voltage range aligns with the system's power source and that the load current requirements fall within the device's continuous output specifications.

Part Context

This model belongs to the LT3692 family of synchronous buck converters designed for medium-power applications. It shares architectural similarities with other members of the series but is distinguished by its specific pinout and thermal characteristics. The device is manufactured using advanced CMOS technology to optimize performance and reliability.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains compatible input voltage ranges and switching frequencies. Verify pin-to-pin compatibility if direct board replacement is intended without schematic modifications.
