LT8643SEV-2#TRPBF

Overview

The LT8643SEV-2#TRPBF is a synchronous step-down Silent Switcher regulator from Analog Devices, housed in a 24-lead LQFN package. It supports an input voltage range of 3.4 V to 42 V and delivers up to 6 A of output current with an adjustable output starting at 0.97 V. The device features a low quiescent current of 750 nA and operates within a switching frequency range of 200 kHz to 3 MHz. It functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

Integrates Silent Switcher architecture for reduced electromagnetic interference without external filters
Provides high efficiency through integrated synchronous rectification
Supports flexible design via external compensation capability

Applications

Industrial automation power systems
Infotainment and body control modules in automotive electronics
Point-of-load regulation for embedded computing platforms

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging distinct from tray variants. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure ordering documentation matches the exact part number to avoid discrepancies in package type or shipping configuration.

Selection Notes

Select this component when a wide input voltage range up to 42 V is required alongside high continuous current delivery. Consider the external compensation feature if precise loop stability optimization is necessary for specific load conditions. Evaluate thermal performance requirements relative to the exposed pad LQFN package for adequate heat dissipation.

Part Context

This part belongs to the LT8643S Silent Switcher family, designed for demanding applications requiring compact size and low noise. It complements other regulators in the series by offering higher current capacity compared to lower-rated siblings while maintaining similar footprint constraints for board space optimization.
