Overview
The LT3680EMSE#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 3.6V to 36V and delivers up to 3.5A of output current. The device features an adjustable output voltage starting at 0.79V, with a maximum limit of 30V. Switching frequency is programmable between 230kHz and 2.45MHz. It utilizes a 10-MSOP package with an exposed pad for thermal management and supports operation across a junction temperature range of -40°C to 125°C.
Feature Summary
- Integrates high-side and low-side power switches for efficient buck conversion without requiring external Schottky diodes.
- Supports wide input voltage ranges suitable for industrial and distributed power bus architectures.
Applications
- Industrial point-of-load regulation
- Distributed power systems
- Battery-powered equipment
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging distinct from tube variants. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure ESD handling protocols are followed during surface-mount assembly due to the small MSOP footprint.
Selection Notes
Select this component when designing circuits requiring high efficiency in compact spaces. Consider the thermal performance provided by the exposed pad for heat dissipation. Evaluate the required switching frequency against electromagnetic interference constraints and passive component size requirements.
Part Context
This part belongs to the LT3680 family of micropower step-down regulators. It shares architectural similarities with other Analog Devices buck converters but is distinguished by its specific current rating and frequency range. It serves as a solution for applications needing robust performance in space-constrained environments.
Replacement Considerations
LT3680EMSE#PBF offers identical electrical specifications but differs in packaging format, utilizing tubes instead of tape-and-reel. Verify compatibility with automated pick-and-place equipment before substitution.
