FAN73894MX onsemi / Fairchild

Here is the English description of the FAN73894MX chip:

• Function: Synchronous Buck DC-DC Controller
• Input Voltage Range: 4.5V to 12V
• Output Voltage: Adjustable 0.8V to 5.5V
• Output Current: Up to 3A
• Switching Frequency: Internal fixed 1.2MHz
• Package: TinySOIC-8

The FAN73894MX from Infineon Technologies is a synchronous buck DC-DC controller capable of driving external MOSFETs to deliver up to 3A of regulated output current.

Key Features:

• Integrated high/low side drivers rated for 3A continuous output
• Narrow 4.5V to 12V input voltage operating range
• Controls external MOSFETs for adjustable 0.8V to 5.5V regulation
• Ultra-small TinySOIC-8 package saves board space
• Internal fixed 1.2MHz switching frequency

Common Applications:

• Low power point-of-load regulation up to 3A
• Primary supply for miniature embedded applications
• Space constrained distributed power systems

Benefits Include:

• Simplifies design/component selection for small solutions
• Optimized for minimal footprint and low voltage applications
• Enables highly integrated 3A controller in the industry's most compact package

Well-suited for applications requiring precise 3A control where controller density, efficiency and board area are extremely limited.

In summary, the FAN73894MX provides 3A capability with best-in-class miniaturization.
