FAN7680 is a synchronous rectifier controller manufactured by Fairchild Semiconductor (FAI).

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.)
