Overview
The FAN23SV06AMPX is a synchronous buck switching regulator IC manufactured by onsemi. It features an adjustable positive output voltage ranging from 0.6V to 5.5V with a maximum continuous output current of 6A. The device operates within an input voltage range of 7V to 18V and supports a switching frequency between 200kHz and 1.5MHz. Packaged in a 34-PowerTFQFN (5.5x5) surface-mount case, it is designed for high efficiency and thermal performance across an operating junction temperature range of -40°C to 125°C.
Feature Summary
- Integrates synchronous rectification with a constant on-time control architecture for efficient power conversion.
- Combines integrated MOSFETs with wide load current capability to support diverse application requirements.
- Includes internal linear regulator functionality without PFM mode operation for stable performance.
Applications
- Point-of-load regulation for digital signal processors
- Power supply stages for memory modules
- General DC-DC conversion in embedded systems
Procurement Notes
Verify the part status carefully as the FAN23SV06P series has been marked obsolete with a final order date notice. Confirm that the AMPX suffix aligns with the specific package and environmental compliance requirements for your design. Cross-reference the manufacturer's latest documentation to ensure compatibility with existing supply chains before finalizing procurement plans.
Selection Notes
Select this component when a 6A synchronous buck solution is required with an input voltage starting at 7V. The adjustable output allows flexibility for various logic levels. Ensure the PCB layout accommodates the 34-PowerTFQFN package dimensions and thermal pad requirements for optimal heat dissipation during operation.
Part Context
This device belongs to the TinyBuck family of single-input integrated synchronous buck regulators. It represents a consolidation of power management functions into a compact footprint, replacing discrete solutions. The series is characterized by its ability to deliver high current density while maintaining simple external component counts.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided data. Due to the obsolete status of the base product, alternative sourcing or redesign may be necessary.
