Features & Applications

The FAN7621 is a pulse frequency modulation controller for high-efficiency half-bridge resonant converters. Offering everything necessary to build a reliable and robust resonant converter, the FAN7621 simplifies designs and improves productivity, while improving performance. The FAN7621 includes a high-side gate-drive circuit, an accurate current controlled oscillator, frequency limit circuit, soft-start, and built-in protection functions. The high-side gate-drive circuit has a common-mode noise cancellation capability, which guarantees stable operation with excellent noise immunity. Using the zero-voltage-switching (ZVS) technique dramatically reduces the switching losses and efficiency is significantly improved. The ZVS also reduces the switching noise noticeably, which allows a small-sized Electromagnetic Interference (EMI) filter. 

Features

  • Variable Frequency Control with 50% Duty Cycle for Half-bridge Resonant Converter Topology
  • High Efficiency through Zero Voltage Switching (ZVS)
  • Fixed Dead Time (350ns)
  • Up to 300kHz Operating Frequency
  • Pulse Skipping for Frequency Limit (Programmable) at Light-Load Condition
  • Remote On/Off Control using CON Pin
  • Protection Functions: Over-Voltage Protection (OVP), Overload Protection (OLP), Over-Current Protection (OCP), Abnormal Over-Current Protection (AOCP), Internal Thermal Shutdown (TSD) 

Applications

  • PDP and LCD TVs
  • Desktop PCs and Servers
  • Adapters
  • Telecom Power Supplies
  • Video Game Consoles
