The FAN3227TMX-F085 from ON Semiconductor is a synchronous three-phase buck regulator controller.

Key Features:

• Integrated high/low side MOSFET gate drivers up to 2.5A per phase
• Narrow 4.5V to 12V input voltage operating range
• Capable of very high efficiency conversion to 0.6V to 5.5V outputs
• VQFN-24 package provides high density 3-phase solution
• Internal 1.6MHz switching converters for each phase

Common Applications:

• High current distributed power systems up to 7.5A total
• Primary supply controller for GPU/FPGA/SoC regulation
• Robust point-of-load supplies for telecom/industrial loads

Benefits Include:

• Enables highest current capacity in ultra-compact footprint
• Optimized for applications with defined lower input voltages
• Allows simpler multi-phase regulator designs at even higher currents

Well-suited for demanding applications up to 7.5A where very high current density is required.

In summary, the FAN3227TMX-F085 offers the industry's leading current handling in the smallest 3-phase solution size.
