Description and Introduction

SECONDARY SUPERVISORY IC The FAN7680 is a synchronous rectifier controller manufactured by Fairchild Semiconductor (FAI). It is designed to drive N-channel MOSFETs in synchronous rectification applications, typically used in switch-mode power supplies (SMPS).  

Key specifications:  
- **Input Voltage Range (VCC):** 4.5V to 30V  
- **Gate Drive Output Voltage:** Up to 10V (for driving MOSFETs)  
- **Operating Frequency Range:** Up to 1MHz  
- **Propagation Delay:** 30ns (typical)  
- **Package:** SOIC-8  
- **Features:** Adaptive dead-time control, UVLO (Under-Voltage Lockout), and overcurrent protection  

The FAN7680 is optimized for high-efficiency power conversion in DC-DC topologies such as flyback and forward converters.  

(Note: Fairchild Semiconductor was acquired by ON Semiconductor in 2016, but the part may still be available under the original manufacturer designation.)
