LTC3809EMSE-1#PBF

DC DC Switching Controllers Overview

The LTC3809EMSE-1#PBF is a synchronous DC/DC controller from Analog Devices Inc., designed for step-down (buck) converter applications. It operates with an input voltage range of 2.75 V to 9.8 V and supports output voltages from 600 mV to 9.8 V. The device features a fixed switching frequency of 550 kHz and delivers up to 5 A output current capability. It utilizes a 10-MSOP package, includes soft-start functionality, and operates within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

Synchronous rectification architecture for high efficiency
Integrated soft-start mechanism
Supports tracking control capabilities

DC DC Switching Controllers Applications

Point-of-load regulation in industrial systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status. Confirm the MSOP-10 package variant matches design requirements. Check manufacturer documentation for latest revision history and environmental certifications before finalizing procurement specifications.

DC DC Switching Controllers Selection Notes

Select this component when a compact synchronous buck solution is required for low-voltage inputs under 10 V. The 550 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Ensure thermal management aligns with the 10-MSOP package constraints for the intended load current.

DC DC Switching Controllers Part Context

This part belongs to the LTC3809 family of synchronous DC/DC controllers. It shares functional similarities with other members like the LTC3809IDD-1 but differs in packaging and pinout configuration. The EMSE-1 designation specifies the MSOP package and specific internal trimming or feature set defined by Analog Devices.
