FAN3226TMX onsemi / Fairchild

Here is the English information on the FAN3226TMX chip:

The FAN3226TMX is a high efficiency DC/DC buck regulator from Texas Instruments.

Key Specifications:

• Input voltage range: 4.5V to 14V
• Output voltage: Adjustable 0.6V to 5.5V
• Maximum current: 3A
• Switching frequency: Up to 2MHz
• Integrated MOSFETs
• I2C interface for digital control/monitoring
• Small 6-pin WSON package

This digitally controlled buck regulator can efficiently step down input voltages to a configurable output between 0.6V to 5.5V at up to 3A of current.

Onboard high/low-side MOSFETs provide regulation with minimal external components.

Programmable switching frequency up to 2MHz allows optimization for size/efficiency.

I2C digital interface enables remote configuration and fault monitoring by an MCU.

Compact 6-pin WSON package maximizes board space efficiency.

Ideal for distributed power in portable computers/devices, industrial equipment and other applications.

In summary, the FAN3226TMX offers a highly integrated digitally controlled buck converter solution.
