您好，1，2是用评估板测试出现的问题吗？建议您用评估板做一下测试。
3，可以接GND，电路请参考BQ25756 Schematic Checklist
BQ25756_Schematic_And_Layout_Checklist.pdf
是我自己设计的板子，暂时买不到开发板，问题1跟2都是在EN_PFM关闭情况下遇到，我理解为当EN_PFM关闭后，不管空载还是带载都是固定频率。然后实际不是。
当EN_PFM开启的时候 带载频率160KHZ 也不为FSW_SYNC设计频率300KH. 是芯片设计如此吗
您好，正在询问更了解这款芯片的TI工程师，稍后回复。
您好
1. Did you also set EN_TERM = 0 for the no load test?2. Is the output prone to overshoot while a load is attached? What are you using as the load?
