FAN23SV15MMPX

Overview

The FAN23SV15MMPX is a synchronous buck regulator manufactured by onsemi, designed for high-efficiency power conversion in compact form factors. It operates with an input voltage range of 7 V to 24 V and provides an adjustable output voltage between 600 mV and 5.5 V. The device supports up to 15 A of continuous output current and features a programmable switching frequency from 200 kHz to 1 MHz. It includes integrated protection mechanisms such as over-current protection and thermal shutdown. The component is housed in a PQFN-34 package, suitable for surface-mount applications, and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Synchronous rectification architecture for enhanced efficiency
• Programmable switching frequency for flexible design optimization
• Integrated over-current and thermal protection circuits

Applications

• Point-of-load (POL) regulation for industrial equipment
• Power supply stages in telecommunications infrastructure
• Voltage regulation for embedded computing systems

Procurement Notes

Verify the specific suffix 'MM' against the official datasheet to confirm pinout and thermal pad configuration. Ensure compatibility with the intended PCB layout due to the PQFN-34 package requirements. Confirm RoHS compliance status through the manufacturer's latest documentation before integration into regulated products.

Selection Notes

Select this component when a single-output synchronous buck converter is required with an input voltage up to 24 V. It is appropriate for designs needing up to 15 A output current with adjustable voltage settings. Consider the PQFN-34 package size constraints and thermal dissipation capabilities relative to the application's ambient temperature conditions.

Part Context

This part belongs to the FAN23SV series of synchronous buck regulators from onsemi. The series is engineered for high-density power management solutions in portable and industrial applications. The FAN23SV15MMPX variant specifically targets higher current demands compared to lower-amperage counterparts in the same family, maintaining similar control features and packaging standards.

Replacement Considerations

Consult the official cross-reference list for direct replacements. Verify that any substitute part matches the 15 A current rating, 7-24 V input range, and PQFN-34 package dimensions to ensure mechanical and electrical compatibility without redesigning the PCB.
