LT8609AHMSE#TRPBF

Overview

The LT8609AHMSE#TRPBF is a synchronous step-down (buck) switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 42 V and provides an adjustable output voltage. The device delivers a continuous output current of 2 A with a 3 A peak capability. Key electrical parameters include a quiescent current of 1.7 uA and a programmable switching frequency ranging from 200 kHz to 2.2 MHz. It functions within a junction temperature range of -40°C to +150°C and is housed in a 16-lead MSOP package.

Feature Summary

Synchronous buck topology for high efficiency
Wide 42V input voltage range
Low quiescent current operation
Programmable switching frequency

Applications

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

Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as distributor listings may contain typos or generic family descriptors. Confirm the specific thermal grade and package variant matches the design requirements. Check for RoHS compliance status directly from the manufacturer datasheet. Ensure the ordering part number aligns with the intended reel or cut tape packaging configuration.

Selection Notes

Select this component when a wide input voltage range up to 42V is required alongside low standby power consumption. The adjustable output voltage allows flexibility for various load requirements. Consider the thermal performance capabilities given the extended operating temperature range up to 150°C. Evaluate the need for synchronization or spread spectrum features if EMI reduction is critical for the application.

Part Context

This part belongs to the LT8609 family of synchronous step-down regulators designed for demanding industrial applications. The family offers various packages and current ratings to suit different board space and power constraints. The HMSE designation indicates a specific MSOP package variant optimized for surface mount assembly.
