LT3695IMSE-5#PBF

Overview

The LT3695IMSE-5#PBF is a micropower step-down switching regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 3.6 V to 36 V and provides a fixed output voltage of 5 V at up to 1 A output current. The device features a single output topology in an MSOP-16 package. Key electrical parameters include a quiescent current of 35 uA, operating supply current of 75 uA, and an adjustable switching frequency from 250 kHz to 2.2 MHz. It supports shutdown functionality and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Fault-tolerant design for robust operation
• Micropower efficiency with low quiescent current
• Adjustable switching frequency for optimization

Applications

• Industrial control systems
• Distributed power architectures
• Battery-powered equipment

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS standards. Confirm the IMSE designation matches the required industrial temperature grade (-40°C to +125°C) and MSOP-16 package type. Ensure the fixed 5V output variant aligns with circuit requirements, as other voltage options exist within the LT3695 family.

Selection Notes

Select this component when a fixed 5V output is required from a wide input range up to 36V. The 1A current capability suits moderate load applications. Consider the MSOP-16 package constraints for PCB layout. Verify that the fault-tolerant feature meets system reliability needs compared to standard buck regulators.

Part Context

This part belongs to the LT3695 series of micropower buck regulators. It shares core architecture with variants like LT3695EMSE-5#PBF but differs in temperature rating (Industrial vs. Extended). It complements higher current devices like the LT3680 or multi-output solutions like the LT3694.

Replacement Considerations

LT3695EMSE-5#PBF serves as a functional equivalent with extended temperature grading.
