FAN73711MX onsemi / Fairchild

Here is the English information on the FAN73711MX chip:

The FAN73711MX is a dual-channel step-down DC-DC converter from Texas Instruments.

Key Specifications:

• Input voltage range: 4.5V to 14V
• Output voltages: 0.6V to 5.5V
• Maximum output current: 2A per channel
• Switching frequency: Up to 2MHz
• I2C digital interface for control/monitoring
• Overvoltage, overcurrent and thermal protection
• Available in 6x6mm QFN package

This dual-channel digital regulator can independently control two output channels via an I2C interface.

It integrates high-side and low-side MOSFETs to enable efficient conversion with few external components.

Onboard protections ensure safe operation under fault conditions.

The I2C interface allows remote configuration and fault reporting to a microcontroller.

Well-suited for space-constrained distributed power architectures in equipment like industrial IoT, medical, computing etc.

The small QFN package maximizes board space efficiency.

In summary, the FAN73711MX provides an easy-to-use dual-channel digitally controlled step-down regulator optimized for distributed power applications.
