FAN6300A Datasheet (ON Semiconductor) - Quasi-Resonant Current Mode PWM Controller

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
