Description and Introduction

Synchronous DC-DC MOSFET Driver The FAN5009M is a DC-DC converter IC manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its key specifications:  

- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage:** Adjustable (typically used for 3.3V or other voltages via external resistors)  
- **Output Current:** Up to 6A  
- **Switching Frequency:** 300kHz  
- **Efficiency:** Up to 95%  
- **Package:** 8-Lead SOIC  
- **Features:**  
  - Synchronous rectification  
  - Integrated MOSFETs  
  - Overcurrent protection  
  - Thermal shutdown  
  - Soft-start function  

This IC is commonly used in point-of-load (POL) power supplies for computing and networking applications.  

(Note: Fairchild Semiconductor was acquired by ON Semiconductor in 2016.)
