Overview
The LT8609AEMSE16#TRPBF is a synchronous step-down (buck) switching regulator from Analog Devices, housed in a 16-lead MSOP package. It operates with an input voltage range of 3V to 42V and delivers a continuous output current of 2A, with a peak capability of 3A. The device features an adjustable output voltage starting from 0.782V and supports programmable switching frequencies between 200kHz and 2.2MHz. It maintains a low quiescent current of 1.7µA and functions within a junction temperature range of -40°C to +150°C.
Feature Summary
- Integrated high-speed synchronous buck topology for efficient power conversion
- Programmable switching frequency allows optimization for size and efficiency
- Extended thermal performance supporting operation up to 150°C junction temperature
Applications
- Industrial distributed power architectures
- Point-of-load regulation for embedded systems
- Battery-powered equipment requiring wide input ranges
Procurement Notes
Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Confirm availability status as supply may be limited or subject to factory order constraints. Ensure the selected package matches the target PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when a compact solution is required for high-voltage input applications. The 16-lead MSOP package offers a balance between thermal dissipation and board space. Consider the 2A continuous current rating relative to the expected load profile and ambient temperature conditions to ensure reliable long-term operation.
Part Context
This part belongs to the LT8609 family of high-efficiency synchronous buck regulators. The family includes variants with different packages such as DFN and MSOP, and fixed or adjustable output options. The LT8609 series is designed to provide robust performance in demanding industrial and commercial environments.
Replacement Considerations
Consult the official datasheet for direct pin-compatible alternatives within the LT8609 family. Verify that any substitute part meets the same input voltage, current, and thermal specifications.
