Overview
The LT3680IMSE#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It accepts input voltages from 3.6V to 36V and delivers up to 3.5A of output current. The device features an adjustable output voltage range from 0.79V to 30V with a single positive output configuration. Operating frequencies are programmable between 230kHz and 2.45MHz. It utilizes a non-synchronous topology and includes thermal protection. The component is housed in a 10-MSOP package with an exposed pad, suitable for surface mount installation across industrial temperature ranges.
Feature Summary
- Integrates a high-efficiency power switch and control logic within a compact monolithic design
- Allows flexible system design through resistor-programmable switching frequency operation
- Provides comprehensive protection mechanisms including thermal shutdown and cycle-by-cycle current limiting
Applications
- Industrial point-of-load regulation
- Battery-powered equipment power management
- General-purpose DC-DC conversion systems
Procurement Notes
Verify the specific suffix and tape/reel or tube packaging requirements against the official datasheet before ordering. Confirm that the 10-MSOP exposed pad footprint matches the target PCB layout dimensions. Ensure the selected variant meets the required operating temperature grade for the intended application environment.
Selection Notes
Select this component when an input voltage range up to 36V is required without synchronous rectification. Consider the trade-off between efficiency and component count, as the non-synchronous design eliminates the need for an external catch diode but may generate more heat at high loads compared to synchronous alternatives.
Part Context
This part belongs to the LT3680 family of step-down regulators designed for wide input voltage applications. It shares architectural similarities with other Linear Technology buck converters but is distinguished by its specific 3.5A current capability and non-synchronous architecture. The IMSE designation indicates the industrial temperature grade and MSOP package style.
Replacement Considerations
Consult official cross-reference documents for direct substitutes. Verify pin compatibility and thermal performance if replacing with similar buck regulators from other manufacturers.
