N901脚(FC2)、脚(FC1)接地,脚为GND(地)。N901脚(SYN)为开关电源工作频率控制端。当脚悬空或接固定电压时,TDA16846将工作于频率自动调整模式。本机采用与脚(内部REF参考电压+5V)
N901 foot (FC2), foot (FC1) ground, the pin is GND (ground). N901 feet (SYN) for the switching power supply frequency control terminal. TDA16846 will work in automatic frequency adjustment mode when the pin is left floating or connected to a fixed voltage. This machine adopts and foot (internal REF reference voltage + 5V)
