LT3430EFE-1#TRPBF

Overview

The LT3430EFE-1#TRPBF is a monolithic step-down DC/DC switching converter manufactured by Analog Devices Inc. It operates with an input voltage range of 5.5V to 60V and supports a maximum output current of 2A. The device features a fixed switching frequency of 100kHz, distinguishing it from the standard LT3430 variant which operates at 200kHz. It utilizes a 16-TSSOP package with an exposed thermal pad for efficient heat dissipation.

Feature Summary

• Integrated 3A internal power switch for high current handling
• Wide input voltage range suitable for various supply sources
• Thermally enhanced package design for improved heat management

Applications

• Industrial control systems requiring stable low-voltage rails
• Automotive electronics operating on wide input voltage ranges
• Point-of-load regulation in compact space-constrained designs

Procurement Notes

Verify the specific suffix '-1' confirms the 100kHz switching frequency requirement, as this differs from the standard LT3430EFE model. Ensure the '#TRPBF' designation matches the required tape and reel packaging format for automated assembly processes. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Selection Notes

Select this component when a lower switching frequency of 100kHz is preferred over the standard 200kHz option to potentially reduce electromagnetic interference or optimize external component selection. The 16-TSSOP-EP package is suitable for applications requiring robust thermal performance within a surface-mount footprint. Consider the 60V maximum input rating against the system's peak supply voltage.

Part Context

This part belongs to the LT3430 family of high-voltage buck converters from Analog Devices. The LT3430 series is designed for versatile DC/DC conversion needs where compact size and wide input voltage compatibility are critical. The -1 suffix specifically denotes the 100kHz frequency variant, while the EFE package indicates the 16-pin TSSOP form factor.

Replacement Considerations

LT3430EFE#TRPBF serves as a functional alternative if a 200kHz switching frequency is acceptable instead of the specified 100kHz. Verify that the pinout and thermal characteristics remain compatible during substitution.
