LTC3851AIGN#PBF

DC DC Switching Controllers Overview

The LTC3851AIGN#PBF is a synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 38 V and supports adjustable output voltages from 800 mV to 5.5 V. The device delivers up to 25 A of output current through a single output channel. Switching frequencies are programmable between 250 kHz and 750 kHz. It functions within a temperature range of -40°C to +125°C and is housed in a 16-lead SSOP package.

DC DC Switching Controllers Feature Summary

• Synchronous buck topology for high-efficiency power conversion
• Programmable switching frequency selection
• Integrated shutdown capability for power management

DC DC Switching Controllers Applications

• Industrial distributed power systems
• Point-of-load regulation modules
• Telecommunications infrastructure power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the SSOP-16 package dimensions against your PCB footprint requirements. Ensure the selected supplier provides valid traceability documentation for the Analog Devices manufacturing lot. Cross-reference the datasheet revision date to confirm parameter accuracy before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a wide input voltage range up to 38 V. The 25 A current capability suits moderate-to-high power point-of-load designs. Consider the 16-SSOP package constraints for thermal dissipation. Verify that the required switching frequency falls within the 250 kHz to 750 kHz operational window for optimal efficiency and component sizing.

DC DC Switching Controllers Part Context

This part belongs to the LTC3851A family of synchronous buck controllers. It shares core architecture with variants like the LTC3851EGN#PBF but differs in package type and temperature rating. The 'IGN' suffix specifically denotes the industrial grade temperature range and SSOP packaging, distinguishing it from other form factors in the same product line.

DC DC Switching Controllers Replacement Considerations

LTC3851EGN#PBF serves as a direct functional substitute with identical electrical specifications, differing primarily in operating temperature range and package availability.
