- Voltage regulation for communication infrastructure equipment
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'M' indicates the tape and reel packaging configuration as documented in official datasheets. Ensure compliance with RoHS and REACH standards by checking the latest regulatory documentation provided by onsemi before integration into production lines.
Selection Notes
Select this regulator when a 10 A synchronous buck solution is required within a 7 V to 18 V input window. Consider the PQFN-34 package dimensions for PCB layout constraints. Evaluate the thermal performance requirements against the specified operating temperature range of -40°C to +125°C. Verify that the desired output voltage falls within the 600 mV to 5.5 V adjustable range.
Part Context
This component belongs to the FAN23SV series of synchronous buck regulators manufactured by onsemi. The series focuses on providing high-current density solutions for modern electronic applications. The FAN23SV10MAMPX specifically targets the 10 A output segment, offering a balance between power handling capability and compact form factor compared to higher current variants in the same family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult onsemi technical support or updated distributor databases for qualified alternatives if this component is discontinued or unavailable.
