LT8609AEDDM-5#TRPBF

Overview

The LT8609AEDDM-5#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 42 V and provides a fixed output voltage of 5 V at a continuous current of 3 A, with peak capability up to 3 A. The device features a switch frequency range from 200 kHz to 2.2 MHz and maintains a low quiescent current of 2.5 uA. It supports shutdown functionality and functions within a junction temperature range of -40°C to +125°C. The component is housed in a compact 10-WFDFN package.

Feature Summary

Synchronous buck topology for high efficiency
Wide 42V input voltage range
Low quiescent current operation
Integrated shutdown control

Applications

Industrial power systems
Distributed power architectures
Point-of-load regulation

Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm pinout compatibility and thermal characteristics. Ensure that the specific ordering code matches the required fixed output voltage and package type. Cross-reference datasheet revisions to validate electrical parameters before integration into final designs.

Selection Notes

Select this component when a fixed 5V output is required from a wide input voltage bus. The DFN-10 package suits space-constrained layouts. Verify thermal performance under maximum load conditions. Confirm that the 2.2 MHz maximum switching frequency aligns with electromagnetic interference requirements.

Part Context

This part belongs to the LT8609 family of high-speed synchronous buck regulators. The 'EDDM' designation indicates the 10-lead DFN package variant. The '-5' suffix specifies the fixed 5V output configuration. The '#TRPBF' suffix denotes tape and reel packaging with lead-free composition.
