LT3697IMSE#TRPBF

Overview

The LT3697IMSE#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5V to 35V and provides an adjustable output voltage from 0.5V to 6.1V. The device delivers a maximum output current of 2.5A in a 16-MSOP package. It features a programmable switching frequency between 250kHz and 2.2MHz, low quiescent current of 40µA, and integrated soft-start functionality.

Feature Summary

• Integrated high-side N-channel MOSFET for efficient synchronous rectification
• Programmable switching frequency allows optimization for size or transient response
• Built-in soft-start limits inrush current during startup
• Thermal regulation protects the device from overheating

Applications

• Point-of-load regulation for industrial equipment
• Power supply stages for embedded computing systems
• Battery-powered portable devices requiring efficient conversion

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability records for quality assurance purposes.

Selection Notes

Select this component when a compact solution is required for converting higher bus voltages to lower logic levels. The adjustable frequency feature enables designers to minimize external passive component sizes while maintaining stable operation under varying load conditions.

Part Context

This part belongs to the LT369x family of micropower buck regulators designed for space-constrained applications. It shares architectural similarities with other members like the LT3693 and LT3695 but offers distinct current handling capabilities suited for mid-range power delivery requirements in modern electronic designs.

Replacement Considerations

LT3697EMSE#PBF serves as a tube-packaged alternative within the same series.
