LT8624SAV#TRPBF

Overview

The LT8624SAV#TRPBF is a synchronous step-down switching regulator from Analog Devices, housed in a 20-lead TFQFN package with an exposed pad. It supports an input voltage range of 3.8 V to 18 V and delivers up to 4 A of output current. The device integrates Silent Switcher architecture for low electromagnetic interference and features an adjustable switching frequency between 200 kHz and 2.2 MHz.

Feature Summary

• Integrates Silent Switcher architecture to minimize radiated electromagnetic emissions
• Combines ultra-low noise reference with synchronous buck topology
• Supports wide input voltage range suitable for various power rails

Applications

• Industrial control systems requiring low noise power supplies
• Battery-powered instrumentation with strict EMI constraints
• Embedded computing platforms needing efficient step-down regulation

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging configuration. Confirm the AV variant matches required thermal and electrical specifications against official datasheets before integration. Ensure compatibility with existing PCB footprint and thermal management design.

Selection Notes

Select this component when low electromagnetic interference is critical alongside high efficiency. The integrated Silent Switcher technology reduces external filtering requirements compared to standard synchronous regulators. Evaluate thermal performance within the TFQFN package for the expected load conditions.

Part Context

This part belongs to the LT8624 family of Silent Switcher regulators designed for applications sensitive to radio frequency interference. It shares architectural similarities with other members in the series but offers specific pinout and performance characteristics defined by the AV suffix and 20-lead form factor.

Replacement Considerations

LT8624SAV#PBF is the leaded equivalent version of this component.
