FAN2306MMPX

Overview

The FAN2306MMPX is a synchronous buck regulator manufactured by Fairchild Semiconductor, now part of onsemi. It operates with an input voltage range of 4.5 V to 18 V and provides an adjustable output voltage from 600 mV to 5.5 V. The device supports a maximum output current of 6 A and features a programmable switching frequency between 200 kHz and 1.5 MHz. It utilizes a PQFN-34 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrated synchronous rectification for high efficiency
• Programmable switching frequency capability
• Adjustable output voltage regulation

Applications

• Point-of-load (POL) conversion in industrial systems
• Power supply stages for embedded computing platforms
• Telecommunications equipment power distribution

Procurement Notes

Verify the manufacturer status as Fairchild Semiconductor has been integrated into onsemi. Confirm that the underscore-to-dash naming convention change does not affect the specific ordering suffix MMPX. Check for end-of-life or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a 6 A synchronous buck solution is required within a 4.5 V to 18 V input window. Ensure the design accommodates the PQFN-34 thermal requirements. Verify that the desired switching frequency falls within the 200 kHz to 1.5 MHz range for optimal performance.

Part Context

This part belongs to the FAN23xx series of synchronous buck regulators designed for compact power management applications. The series is characterized by high integration and efficiency, suitable for space-constrained designs requiring robust voltage regulation capabilities.

Replacement Considerations

Consult onsemi documentation for updated part numbers following the Fairchild integration. Cross-reference tools may list equivalent parts, but verify pinout and electrical specifications against the official datasheet.
