LT3684IMSE#TRPBF

Overview

The LT3684IMSE#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7V to 36V and delivers up to 2A of output current. The device features a fixed internal switching frequency of 2.8MHz, enabling the use of small external components. It includes integrated power switches, soft start, and cycle-by-cycle current limit protection. The component is housed in a thermally enhanced MSOP-10 package and supports operation temperatures from -40°C to +125°C.

Feature Summary

Synchronous rectification architecture for high efficiency across load ranges
Integrated 2.8MHz fixed switching frequency minimizes passive component size
Built-in soft-start limits inrush current during startup
Cycle-by-cycle current limiting protects against short circuits

Applications

Industrial control systems requiring compact power solutions
Battery-powered equipment needing efficient voltage regulation
Embedded systems with limited board space constraints
Automotive electronics operating within wide input voltage ranges

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the IMSE variant matches the required thermal performance and pinout for your PCB layout. Check current availability status as supply levels may fluctuate. Ensure compatibility with your target input voltage and load requirements before finalizing procurement orders.

Selection Notes

Choose this regulator when space efficiency is critical due to its high 2.8MHz frequency. It suits applications requiring stable 2A output from varying input sources. Consider the MSOP-10 package for thermal management needs. Evaluate if the fixed frequency meets EMI requirements compared to adjustable frequency alternatives.

Part Context

This part belongs to the LT3684 family of synchronous buck regulators. It shares design principles with other Analog Devices PMICs focusing on integration and miniaturization. The IMSE designation specifies the industrial temperature grade and MSOP package type. It complements lower current or higher voltage variants in the broader portfolio.
