LT3680EMSE#PBF

Overview

The LT3680EMSE#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It accepts input voltages up to 36V and delivers an adjustable output voltage ranging from 0.79V to 30V with a maximum output current of 3.5A. The device operates at a programmable switching frequency between 230kHz and 2.45MHz. It features a quiescent current of 75µA, synchronous rectification, and thermal regulation. The component is housed in a 10-MSOP package with an exposed pad and supports operation temperatures from -40°C to 125°C.

Feature Summary

Integrates a high-efficiency power switch and synchronous rectifier to eliminate the need for external catch diodes.
Features programmable switching frequency allowing optimization for efficiency or external component size.
Includes thermal regulation circuitry that reduces output current when junction temperature exceeds safe limits.

Applications

Industrial point-of-load regulation
Distributed power systems
Battery-powered equipment

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the MSOP-10 package dimensions match the PCB footprint requirements. Ensure the selected switching frequency configuration aligns with the intended inductor selection for optimal performance.

Selection Notes

Select this component for applications requiring a wide input voltage range up to 36V and moderate output currents. Consider the thermal management capabilities provided by the exposed pad design. Evaluate the required output voltage range against the minimum reference voltage specification.

Part Context

This part belongs to the LT3680 family of step-down switching regulators designed for high-efficiency power conversion. It is distinct from other variants like the LT3680HMSE#PBF which may differ in temperature grades or packaging options within the same functional series.
