LT3431IFE#PBF

Overview

The LT3431IFE#PBF 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 60V. The device supports adjustable output voltages down to 0.8V using external resistors. It features a fixed 500kHz switching frequency and offers cycle-by-cycle current limiting and thermal shutdown protection. The component is housed in a thermally enhanced 16-lead SSOP package.

Feature Summary

Integrated synchronous rectification for improved efficiency
Wide input voltage capability up to 60V
Built-in thermal and current protection mechanisms

Applications

Industrial control systems
Battery-powered equipment
Point-of-load regulation modules

Procurement Notes

Verify the exact suffix PBF indicates lead-free compliance when sourcing. Confirm the SSOP-16 package variant matches your PCB footprint requirements. Ensure the operating temperature range aligns with your specific environmental conditions before finalizing procurement orders.

Selection Notes

Select this component for applications requiring wide input voltage ranges and moderate output currents. Consider the fixed 500kHz frequency for inductor size optimization. Evaluate thermal performance needs due to the integrated switch design and ensure adequate board space for the SSOP package.

Part Context

This part belongs to the LT343x family of synchronous buck converters. It shares architectural similarities with other members but is distinguished by its specific input voltage limits and pin configuration. The series targets robust industrial and commercial power management solutions.

Replacement Considerations

Direct replacements include the LT3431EFE#PBF for the SOIC-16 package variant. Cross-reference electrical specifications carefully as package differences may impact thermal dissipation characteristics and physical mounting constraints.
