Overview
The LT3580MPMS8E#TRPBF is a monolithic synchronous step-down DC/DC converter from Analog Devices Inc., designed for high-efficiency power conversion in space-constrained applications. It integrates two N-channel power switches and operates with an input voltage range of 2.7V to 16V. The device delivers up to 4A of output current with precise regulation. Key electrical parameters include a switching frequency adjustable from 100kHz to 1.5MHz, ensuring compatibility with various passive component selections. It features low dropout operation and supports external synchronization. The MSOP-8 package provides thermal performance suitable for dense PCB layouts.
Feature Summary
- Integrated dual synchronous rectification architecture for enhanced efficiency
- Wide input voltage range supporting diverse power sources
- Adjustable switching frequency for optimized filter size and transient response
- Compact surface-mount packaging facilitating automated assembly
Applications
- Portable battery-powered equipment requiring efficient voltage regulation
- Industrial control systems needing stable DC bus voltages
- Embedded computing modules with strict space limitations
Procurement Notes
Verify the exact suffix 'MPMS8E' matches your board footprint and thermal requirements. Confirm that the 'TRPBF' designation indicates tape-and-reel packaging compatible with your pick-and-place machinery. Ensure the manufacturer source is authorized to guarantee authenticity and traceability of the military-grade variant.
Selection Notes
Select this component when input voltages vary significantly between 2.7V and 16V while maintaining high efficiency at moderate loads. Consider the MSOP-8 package constraints regarding thermal dissipation and available PCB area. Evaluate the need for external synchronization if multiple converters operate in close proximity to prevent audible noise or interference.
Part Context
This part belongs to the LT3580 family of synchronous buck converters. It shares architectural similarities with other members but offers specific pinout and thermal characteristics defined by the MSOP-8 package. The military grade (MP) variant ensures extended temperature range compliance and reliability standards distinct from commercial equivalents.
Replacement Considerations
Direct substitutes include other LT3580 variants with different packages or grades, such as LT3580HMS8E or LT3580IMS8E, provided pin compatibility is verified. Cross-reference with competitor parts like those from Maxim Integrated or Texas Instruments only after confirming equivalent electrical specifications and thermal performance.
