LT3695IMSE#PBF

Overview

The LT3695IMSE#PBF is a micropower step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6 V to 36 V and provides a fixed 5 V output at up to 1 A. The device features a low quiescent current of 35 uA and supports adjustable switching frequencies from 250 kHz to 2.2 MHz. Packaged in a 16-lead MSOP, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Fault-tolerant operation allows the device to withstand short circuits on the output without damage.
• Micropower architecture ensures minimal energy consumption during standby or light-load conditions.
• Integrated synchronous rectification improves conversion efficiency across various load levels.

Applications

• Portable battery-powered equipment requiring efficient power management
• Industrial control systems operating under variable input conditions
• Embedded computing modules needing stable regulated voltage rails

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm package integrity for the MSOP-16 form factor upon receipt. Ensure environmental specifications match operational requirements. Cross-reference datasheet revisions for any functional updates. Validate supplier authenticity through authorized distribution channels.

Selection Notes

Choose this component for designs requiring high input voltage tolerance combined with low standby power. The fixed 5 V output simplifies design for standard logic interfaces. Consider thermal performance given the small MSOP package size. Evaluate external component selection based on the specified frequency range.
