Features
* to enhance the performance of flyback converters. FAN6300A is applied on quasiresonant flyback converters where maximum operating frequency is below 100 kHz. FAN6300H is suitable for high
* frequency operation (up to 190 kHz). A built
* in HV startup circuit can provide more startup curr
Applications
* AC/DC NB Adapters
* Open
* Frame SMPS
