LT3970EMS#PBF

Overview

The LT3970EMS#PBF is a monolithic buck switching regulator from Analog Devices, housed in a 10-lead MSOP package. It accepts an input voltage range of 4.2V to 40V and delivers up to 350mA output current. The device features an adjustable switching frequency from 200kHz to 2.2MHz and a low quiescent current of 1.8uA. Operating temperature spans -40°C to +125°C.

Feature Summary

Adjustable switching frequency allows optimization for efficiency or component size.
Low quiescent current supports extended battery life in portable applications.
Wide input voltage range accommodates various power source configurations.

Applications

Battery-powered equipment requiring efficient step-down conversion
Industrial control systems with wide input voltage variations
Portable instrumentation and measurement devices

Procurement Notes

Verify the specific suffix and tape/reel versus tube packaging options available from authorized distributors. Confirm RoHS compliance status and lead-free soldering requirements for your assembly process. Check for any regional distribution restrictions or supply limitations that may affect procurement timelines.

Selection Notes

Select this component when a wide input voltage range up to 40V is required alongside low standby current consumption. The adjustable frequency feature enables trade-offs between external component size and noise performance. Ensure the thermal characteristics of the MSOP package meet the thermal dissipation needs of the target application environment.

Part Context

This part belongs to the LT3970 series of high-voltage buck regulators designed for space-constrained applications. It complements other Analog Devices power management solutions by providing a compact, efficient step-down topology suitable for both fixed and adjustable output voltage configurations within the same family.

Replacement Considerations

LT3970IMS#PBF offers similar electrical specifications but utilizes a TSSOP-10 package instead of MSOP-10. Verify pinout compatibility and thermal pad requirements before substitution. Other series members like LT3971 provide higher current capabilities but differ in package and input voltage ranges.
