LT8609AHDDM-5#PBF

Overview

The LT8609AHDDM-5#PBF is a synchronous step-down switching regulator from the LT8609 family, manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 42V and provides a fixed output voltage of 5V. The device supports a continuous output current of 3A with a peak capability of 3A. It features a switchable frequency range from 200kHz to 2.2MHz and maintains a low quiescent current of 2.5µA. The component is housed in a DFN-10 package and is rated for operation between -40°C and +150°C.

Feature Summary

Synchronous buck topology for high efficiency
Wide input voltage range supporting automotive and industrial supplies
Adjustable switching frequency for optimization
Low quiescent current for standby applications

Applications

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

Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and thermal characteristics. Ensure the DFN-10 package matches your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's datasheet before finalizing procurement specifications.

Selection Notes

Select this part when a 5V output is required from a wide input range up to 42V. The 3A current rating suits moderate load applications. Consider the DFN-10 package size for space-constrained designs. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This component belongs to the LT8609 series of ultra-low EMI synchronous buck regulators. It is designed for compact, high-efficiency DC-to-DC conversion. The series includes variants with different output voltages and packages, sharing common control architecture and protection features.
