LTC1159CS-5#PBF

DC DC Switching Controllers Overview

The LTC1159CS-5#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 40 V and delivers up to 10 A output current at a fixed 5 V output. The device features a 250 kHz switching frequency, 20 uA quiescent current, and supports shutdown functionality. Packaged in a 16-pin SOIC, it is designed for high-efficiency DC/DC conversion applications.

DC DC Switching Controllers Feature Summary

• Synchronous buck topology for enhanced efficiency
• Automatic Burst Mode operation for low load performance
• Integrated shutdown control capability

DC DC Switching Controllers Applications

• Industrial power supplies
• Distributed power systems
• Point-of-load regulation

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the -5 variant corresponds to the fixed 5 V output specification. Ensure the SOIC-16 package dimensions match your PCB footprint requirements before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring high current delivery from wide input voltage ranges. The fixed 5 V output simplifies design compared to adjustable variants. Consider thermal management needs given the 10 A capability and SOIC-16 package constraints in dense layouts.

DC DC Switching Controllers Part Context

This part belongs to the LTC1159 family of synchronous step-down controllers. It shares core architecture with other variants like the LTC1159CG-5 but differs in package type and pinout configuration. The CS-5 designation specifically identifies the commercial temperature range and fixed 5 V output version within the broader product line.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other Analog Devices synchronous buck controllers with similar current ratings and input voltage ranges. Verify compatibility regarding switching frequency, feedback resistor values, and thermal performance when considering alternative parts.
