FAN2306MMPX

Overview

The FAN2306MMPX is a highly efficient integrated synchronous buck regulator manufactured by onsemi. It operates with an input voltage range from 4.5 V to 18 V and delivers up to 6 A of output current. The device features adjustable switching frequencies between 200 kHz and 1.5 MHz, allowing for optimization of external component size and efficiency. It provides an adjustable output voltage range from 600 mV to 5.5 V. The regulator includes a shutdown function and low quiescent current of 18 uA. It is housed in a 34-pin PQFN-34 (5x5.5 mm) package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Integrated synchronous buck topology for high efficiency
• Wide input voltage range supporting various power sources
• Adjustable switching frequency for design flexibility
• Compact surface-mount packaging for space-constrained applications

Applications

• Point-of-load regulation in industrial systems
• Power supply stages for embedded computing platforms
• Telecommunications equipment power distribution
• Consumer electronics requiring efficient DC-DC conversion

Procurement Notes

Verify the exact suffix 'MMPX' against the manufacturer's official datasheet to confirm pinout, thermal pad configuration, and specific electrical tolerances. Ensure compatibility with your PCB footprint and thermal management strategy. Check for end-of-life status or alternative recommendations directly from onsemi documentation before finalizing procurement plans.

Selection Notes

Select this component when a compact, high-current synchronous buck solution is required within a 4.5 V to 18 V input window. Consider the adjustable frequency range to balance EMI performance against passive component size. Verify that the 6 A continuous current rating meets peak load demands while accounting for thermal dissipation in the PQFN-34 package under your specific ambient conditions.

Part Context

This part belongs to the FAN2306 series of high-efficiency synchronous buck regulators from onsemi. The series is designed for applications demanding high power density and wide input voltage ranges. The MMPX suffix typically denotes a specific tape-and-reel packaging variant intended for automated assembly processes, distinguishing it from other package or quantity options within the same functional family.

Replacement Considerations

Consult onsemi's official cross-reference tools for verified substitutes. Potential alternatives may include other members of the FAN2306 family or comparable synchronous buck regulators from other manufacturers, provided they match the 6 A current rating, 18 V max input, and 34-pin PQFN footprint. Always validate pin-to-pin compatibility and thermal characteristics before substitution.
