The FAN3226TMX-F085 from ON Semiconductor is a synchronous two-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 delivering very high efficiency to 0.6V to 5.5V outputs
• VQFN-20 package provides compact solution size
• Internal 1.6MHz switching converter for each phase

Common Applications:

• High current distributed power systems up to 5A total
• Primary supply controller for GPU/FPGA/SoC regulation
• Point-of-load supplies for network/telecom systems

Benefits Include:

• Achieves very high current capacity in small solution size
• Optimized for applications within defined voltage range
• Enables simpler, lower cost multi-phase regulator designs

Well-suited for high current applications up to 5A where a two-phase controller in a small footprint is required.
