FAN2365MPX

Overview

The FAN2365MPX is a high-efficiency integrated synchronous buck regulator from onsemi. It operates with an input voltage range of 4.5 V to 24 V and supports up to 15 A continuous load current. The device utilizes constant on-time control architecture for stable performance. It features a positive adjustable output starting at 0.6 V, providing a single output channel. Packaged in a 34-PowerTFQFN, it is designed for point-of-load regulation applications requiring high power density.

Feature Summary

• Integrates synchronous rectification for enhanced efficiency
• Employs constant on-time control topology
• Supports wide input voltage range up to 24 V
• Delivers high continuous output current capability

Applications

• Point-of-load (PoL) regulators
• Industrial equipment power distribution
• Telecommunications infrastructure
• Computing system power management

Procurement Notes

Verify the specific suffix MPX against the official datasheet to confirm package type and tape-and-reel specifications. Confirm end-of-life status as some sources indicate discontinuation. Ensure compatibility with existing PCB footprints for the 34-PowerTFQFN package before procurement.

Selection Notes

Select this component when a wide input voltage range up to 24 V is required alongside high current delivery. The synchronous design suits applications prioritizing thermal efficiency. Verify that the constant on-time control meets the transient response requirements of the specific load dynamics.

Part Context

This part belongs to onsemi's portfolio of switching voltage regulators. It is designed for power management systems needing robust step-down conversion. The device integrates power switches to reduce external component count compared to non-integrated solutions.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family. Verify if newer generations offer improved thermal performance or updated packaging options while maintaining electrical equivalence.
