FAN6300A - Quasi-Resonant Current Mode PWM Controller
1 DET This pin is connected to an auxiliary winding of the transformer via resistors of the divider for the following purposes: * Generates a ZCD signal once the secondary *side switching current falls to zero.
* Produces an offset voltage to compensate the threshold volta
FAN6300A 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
