LT8609AJDDM-5#TRPBF

Overview

The LT8609AJDDM-5#TRPBF is a synchronous step-down switching regulator from Analog Devices, housed in a 10-WFDFN package. It delivers a fixed 5 V output with a continuous current capability of 3 A and a peak current of 3 A. The device accepts an input voltage range from 3 V to 42 V. It features a low quiescent current of 2.5 uA and supports adjustable switching frequencies between 200 kHz and 2.2 MHz. Operating junction temperatures range from -40°C to +150°C.

Feature Summary

Synchronous buck topology for high-efficiency power conversion
Integrated shutdown control for power management
Wide input voltage range supporting diverse supply sources
Adjustable switching frequency for optimization

Applications

Industrial point-of-load regulation
Battery-powered equipment power supplies
General-purpose DC-DC conversion systems

Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging distinct from tube variants. Confirm the 'A' grade designation matches required performance specifications. Ensure the DFN-10 footprint aligns with PCB layout constraints. Validate RoHS compliance status against current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5 V output is required from higher voltage rails up to 42 V. The 3 A continuous current rating suits moderate load applications. Consider the 10-WFDFN package size for space-constrained designs. Evaluate the 2.5 uA quiescent current for battery life efficiency requirements in standby modes.

Part Context

This part belongs to the LT8609 family of micropower synchronous buck regulators. It shares core architectural features with other variants in the series but differs in output voltage configuration and packaging options. The LT8609 series is designed for applications requiring high efficiency and low standby current across wide input ranges.
