Overview
The FAN23SV65MPX is a synchronous buck regulator from onsemi, designed for high-current applications. It features an integrated power stage capable of delivering up to 15 A output current. The device operates with an input voltage range of 4.5 V to 28 V and supports adjustable output voltages from 0.6 V to 5.5 V. Key electrical parameters include a switching frequency range of 200 kHz to 1 MHz and a quiescent current of 24 µA. It is housed in a PQFN-34 package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Integrates a synchronous buck power stage with internal high-side and low-side MOSFETs for compact design.
- Supports wide input voltage ranges suitable for various bus architectures.
- Includes programmable soft-start and frequency synchronization capabilities.
Applications
- Point-of-load (POL) conversion for server and data center processors
- Industrial equipment power distribution
- Telecommunications infrastructure bias supplies
Procurement Notes
Verify the specific suffix 'AMPX' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS and REACH requirements as stated in the component documentation. Cross-reference the part number with the latest product change notices to confirm availability status and any potential obsolescence warnings before finalizing procurement plans.
Selection Notes
Select this component when a single-channel synchronous buck solution is required for currents up to 15 A. Consider the PQFN-34 package size constraints and thermal dissipation requirements relative to the application environment. Evaluate the need for external compensation components versus internal fixed-frequency operation based on system stability requirements.
Part Context
This part belongs to the FAN23SV series of synchronous buck regulators. It shares architectural similarities with other members like the FAN23SV70AMPX but differs in specific current ratings and packaging options. The series is targeted at high-efficiency power management solutions requiring small form factors and robust performance under varying load conditions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's official replacement guide or contact technical support directly for verified alternatives if this component is obsolete or unavailable.
