Overview
The LT1576CS8#PBF is a step-down switching regulator manufactured by Analog Devices Inc., housed in an 8-lead SOIC package. It operates with an input voltage range of 5 V to 25 V and delivers a fixed output voltage of 5 V at a maximum current of 1.5 A. The device functions at a fixed switching frequency of 200 kHz and includes shutdown capability. It supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Fixed 200 kHz switching frequency for consistent electromagnetic interference performance
- Integrated shutdown pin for power management control
- High efficiency buck topology suitable for wide input voltage ranges
Applications
- Point-of-load regulation in industrial systems
- Battery-powered equipment requiring efficient step-down conversion
- Telecommunications infrastructure power distribution
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Check current availability status as supply may be limited or subject to factory order constraints. Ensure the fixed 5V output aligns with your system design needs, as adjustable variants exist within the series.
Selection Notes
Select this component when a fixed 5V output is required from a 5V to 25V input source. The 1.5A output current capacity suits moderate load applications. Consider the 200kHz frequency for balancing component size and efficiency. Verify thermal performance within the -40°C to +125°C range for your specific enclosure environment.
Part Context
This part belongs to the LT1576 series of high-efficiency buck regulators. It shares architectural similarities with other members like the LT1578 but differs in output configuration and current ratings. The CS8 designation specifies the commercial temperature grade and SOIC-8 package type.
Replacement Considerations
LT1576IS8-5#PBF offers identical electrical specifications with an extended industrial temperature range (-40°C to +125°C). Verify package compatibility and thermal characteristics when substituting between commercial and industrial grades.
