Overview
The LT3695IMSE#TRPBF 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 currents.
Applications
- Battery-powered portable electronic devices requiring efficient power management
- Industrial control systems operating within wide input voltage ranges
- Embedded systems utilizing microprocessors or memory components needing stable 5V rails
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm that the IMSE variant meets the required industrial temperature specifications for your application environment. Cross-reference the manufacturer's latest datasheet to ensure compliance with current RoHS directives and material declarations before finalizing procurement plans.
Selection Notes
Select this component when a fixed 5V output is required from a high-voltage input source. The wide input range accommodates single-cell lithium-ion batteries or unregulated supplies. Ensure the thermal design supports the 1A output capability within the specified MSOP package constraints for reliable long-term operation.
Part Context
This part belongs to the LT3695 family of micropower buck regulators designed for space-constrained applications. It integrates a 1A switch and offers fault tolerance, distinguishing it from standard non-fault-tolerant regulators in the same series. The MSOP-16 package provides a compact footprint suitable for dense PCB layouts.
Replacement Considerations
LT3695IMSE-5#PBF is a tube-packaged equivalent offering identical electrical performance. Verify that the packaging format change does not impact automated assembly processes. No functional differences exist between the reel and tube versions regarding electrical characteristics.
