LT3430IFE-1#PBF

Overview

The LT3430IFE-1#PBF is a high-voltage, 3A step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5.5V to 60V and features a fixed 100kHz switching frequency. The device provides an adjustable output voltage with a maximum continuous output current of 2.75A. It utilizes current-mode control architecture for stable performance. The component is housed in a TSSOP-EP-16 package and supports operation across a temperature range of -40°C to +125°C.

Feature Summary

Integrated high-voltage power switch capable of handling up to 60V input
Fixed 100kHz switching frequency reduces external component size
Current-mode control architecture ensures fast transient response
Adjustable output voltage allows flexible system design

Applications

Industrial point-of-load regulation
Automotive electronics systems
Distributed power architectures
High-voltage battery-powered equipment

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm RoHS compliance status through official documentation. Ensure the 100kHz frequency variant matches the design requirement, as other variants exist within the series. Validate thermal management requirements for the TSSOP-16 package under full load conditions.

Selection Notes

Select this part for applications requiring high input voltages up to 60V with moderate current demands. The fixed 100kHz frequency is suitable for minimizing passive component footprint compared to higher-frequency alternatives. Consider the thermal dissipation capabilities of the exposed pad package for high-power density designs.

Part Context

This component belongs to the LT3430 family of high-voltage buck converters. It is designed for robust performance in demanding environments. The manufacturer offers related variants with different switching frequencies or pin configurations to suit diverse application needs within the same product line.
