LT8606HMSE#PBF

Overview

The LT8606HMSE#PBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 42 V and delivers a continuous output current of 350 mA. The device features a low quiescent current of 2.5 µA and supports adjustable switching frequencies from 200 kHz to 2.2 MHz. It utilizes an MSOP-10 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Synchronous buck topology for high efficiency
• Low quiescent current operation
• Adjustable switching frequency capability

Applications

• Industrial control systems
• Automotive electronics
• Point-of-load regulation

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS standards. Confirm the MSOP-10 package variant matches design requirements. Check official Analog Devices documentation for latest lifecycle status, as availability may be restricted or subject to factory orders. Ensure thermal management aligns with the specified operating temperature range.

Selection Notes

Select this component when a compact solution is required for 42V input systems needing moderate current. The 350mA rating suits applications where space is limited but efficiency is critical. Compare against higher current variants like the LT8607 if load demands exceed 350mA. Consider the fixed frequency options versus adjustable ranges based on EMI constraints.

Part Context

This part belongs to the LT8606 family of micropower synchronous step-down regulators. It shares architectural similarities with other members like the LT8608 and LT8610, differing primarily in current handling capabilities and package configurations. The series is designed for applications requiring low standby power consumption.

Replacement Considerations

LT8606EMSE#PBF offers identical electrical specifications in an MSOP-10 package. LT8606BDC#TRMPBF provides similar performance in a DFN-8 package with tape-and-reel packaging.
