LT8642SIV#PBF

Overview

The LT8642SIV#PBF is a synchronous step-down Silent Switcher 2 regulator from Analog Devices, housed in a 24-lead LQFN package. It operates with an input voltage range of 3.4 V to 18 V and delivers up to 10 A of output current. The adjustable output voltage allows for flexible system design. The device supports switching frequencies between 200 kHz and 3 MHz and maintains a quiescent current of 155 uA. It functions within a temperature range of -40°C to +85°C.

Feature Summary

Integrates Silent Switcher 2 technology to minimize electromagnetic interference radiation without requiring external filters.
Features synchronous buck topology for high efficiency across wide load ranges.
Includes internal compensation and soft-start capabilities to simplify circuit design.

Applications

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

Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS standards before procurement. Confirm the IV suffix indicates the correct operating temperature range for your application environment. Ensure the LQFN-24 footprint matches your PCB layout requirements. Check current distributor availability as supply status may vary.

Selection Notes

Select this component when an 18V input limit and 10A continuous current are required. Choose the IV suffix for standard industrial temperature applications. Consider the LT8642SEV#PBF if a higher maximum junction temperature rating is necessary for your thermal design constraints.

Part Context

This part belongs to the LT8642S Silent Switcher 2 family, designed for high-efficiency DC/DC conversion. It shares architectural similarities with other members like the LT8640S but differs in input voltage ratings and current capabilities. The series emphasizes compact size and low EMI performance for dense power designs.

Replacement Considerations

The LT8642SEV#PBF serves as a verified alternative within the same family, offering identical electrical specifications but with an extended maximum operating temperature range up to 125°C. Verify pinout compatibility during substitution.
