Part Number: UCC2897A Other Parts Discussed in Thread: PMP9656 , UCC27511 Hi sir:
请问正激电路中变压器副边整流电路的耐压是按照什么选择?
是按照 输入除以变压器匝数比的副边电压选择还是正激电路输出电压选择?
UCC2897A应用手册中提到,QF自驱动耐压是按照副边电压;
PMP9656参考设计中的选型应该是按照输出电压来的,器件耐压达不到副边电压。
Part Number: UCC2897A Hi Ti ,
I have some questions for you about UCC2897 when turn off transient .
1. I measure the AUX pin duty value about 100ns ,the duty almost > 95% it will excess the setting(86%)?( Ron/Roff setting : Ron=130kohm , Roff=18kohm…
