The FAN7621S is a pulse frequency modulation controller for high energy efficiency half-bridge resonant converters. The FAN7621S provides everything needed to build a reliable and robust resonant converter, simplifying design and increasing productivity and performance. FAN7621S includes high side gate drive circuit, accurate current controlled oscillator, frequency limit circuit, soft start and built-in protection functions. This high-side gate drive circuit features common-mode noise suppression, ensuring stable operation and excellent noise immunity. The use of Zero Voltage Switching (ZVS) technology greatly reduces switching losses and significantly improves energy efficiency. ZVS also significantly reduces switching noise, allowing the use of small electromagnetic interference (EMI) filters. FAN7621S can be applied in various resonant converter topologies such as series resonant, parallel resonant and LLC resonant converters.
