• Package: 4mm x 4mm QFN

The FAN3227CMPX from Infineon Technologies is a synchronous buck DC-DC controller capable of driving external MOSFETs to deliver up to 1.5A of regulated output current.

Key Features:

• Integrated high/low side drivers rated for 1.5A continuous output
• Wide 3.5V to 14V input voltage operating range
• Controls external MOSFETs for adjustable 0.6V to 5.5V regulation
• Compact 4mm x 4mm QFN package
• Internal fixed 1.2MHz switching frequency

Common Applications:

• Embedded/space constrained point-of-load regulation
• Battery-powered device primary power supply
• Low power board supplies up to 1.5A

Benefits Include:

• Allows flexible low voltage input compatibility
• Simplifies design for density optimized 1.5A solutions
• Enables highly integrated controller in ultrasmall footprint

Well-suited for applications requiring up to 1.5A output where board area, input range and thermal management are critical constraints.

In summary, the FAN3227CMPX provides leading density with balanced performance and footprint.
