آی سی FAN6300A جهت کنترل سرعت فن مادربرد با ستفاده از روش PWM مورد استفاده قرار می گیرد. و از نوع sop-8 می باشد.
The highly integrated FAN6300A/H of PWM controller provides several features to enhance the performance of flyback converters.
FAN6300A is applied on quasiresonant flyback converters where maximum operating frequency is below 100kHz.
FAN6300H is suitable for high-frequency operation (up to 190kHz).
A built-in HV startup circuit can provide more startup current to reduce the startup time of the controller.
Once the VDD voltage exceeds the turn-on threshold voltage, the HV startup function is disabled immediately to reduce power consumption.
An internal valley voltage detector ensures power system operates at quasi-resonant operation over a wide-range of line voltage and any load conditions, a
