Overview
The CS51413GD8G is a synchronous step-down DC-DC converter designed for automotive applications. It operates with an input voltage range of 4.5V to 40V and delivers up to 1.5A output current in a single-output configuration. The device utilizes a fixed switching frequency architecture and is housed in an 8-pin SOIC package (SOICN) with a width of 3.90mm. It features integrated protections suitable for harsh automotive environments, ensuring reliable power management for downstream electronics.
Feature Summary
- Synchronous rectification architecture for improved efficiency
- Automotive-grade qualification for reliability
- Wide input voltage range supporting various supply conditions
- Integrated protection mechanisms for system safety
Applications
- Automotive infotainment systems
- Instrument cluster power distribution
- ADAS sensor power supplies
- Body control module regulation
Procurement Notes
Verify the complete part number including suffixes such as 'G' for lead-free status when ordering. Confirm the specific package variant matches the design requirements. Ensure compatibility with existing thermal management solutions given the SOICN footprint. Cross-reference official datasheets for exact electrical specifications before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring a compact, automotive-rated synchronous buck regulator. It is suitable where input voltages fluctuate between 4.5V and 40V. Consider the 1.5A current limit for moderate load requirements. Evaluate thermal performance within the 8-SOIC package constraints for the intended enclosure environment.
Part Context
This device belongs to onsemi's automotive power management portfolio, specifically the synchronous step-down converter family. It complements other PMICs by providing efficient voltage regulation for low-power automotive subsystems. The series emphasizes robustness and compliance with automotive industry standards for electronic components used in vehicle networks.
Replacement Considerations
Check for direct pin-compatible alternatives within the same product family that may offer updated revisions or different thermal characteristics. Verify if newer generations provide enhanced efficiency or additional protection features while maintaining the 8-SOIC form factor.
