bq500212的频率问题

Other Parts Discussed in Thread: BQ51013B, BQ500212A

我用bq500212a+bq51013b做了demo板,测试发现达不到5w,在1W时,线圈发射和接收频率就达到了200khz,输出电压降到4.83V。我想请教几个问题:

1、怎么判断是发射板问题还是接收板问题?

2、能不能给出输出500mA/1A时,发射线圈和接收线圈的正确波形?

3、线圈的正常频率该是多少?频率是根据功率自动调节的吗?

4、功率达不到的原因有哪些,我接收板的线圈13uH,与电感的串联电容C1是200nf,C2是1.8nF||100pF。

非常感谢~
