LT8609SIV#TRPBF

Overview

The LT8609SIV#TRPBF is a synchronous step-down switching regulator from Analog Devices, operating within a 3V to 42V input voltage range. It delivers a continuous output current of 2A with a peak capability of 3A. The device features an adjustable output voltage and supports programmable switching frequencies between 200kHz and 2.2MHz. It operates in an extended temperature range from -40°C to +125°C and utilizes an LQFN-16 package.

Feature Summary

• Integrated synchronous buck topology for high efficiency
• Programmable switching frequency for optimization
• Extended automotive-grade temperature operation

Applications

• Automotive battery systems
• Industrial power supplies
• Point-of-load regulation

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the LQFN-16 package dimensions against your PCB footprint requirements. Ensure the selected switching frequency configuration meets your electromagnetic interference constraints. Validate that the 2A continuous current rating satisfies your maximum load demands under all thermal conditions.

Selection Notes

Select this component for applications requiring wide input voltage compatibility up to 42V. The adjustable output voltage allows flexibility for various logic levels. Consider the LQFN-16 package for space-constrained designs. Verify thermal performance at the chosen switching frequency and load current to ensure operation within the specified junction temperature limits.

Part Context

This part belongs to the LT8609 family of high-voltage synchronous buck regulators. It shares core architecture with variants like LT8609AJDDM-5#PBF but differs in package type and fixed versus adjustable output configurations. The SIV suffix denotes the specific LQFN-16 package variant designed for surface mount assembly.

Replacement Considerations

LT8609SIV#PBF is the tray-packaged equivalent of this reel-part.
