1、一般该芯片设置的工作频率一般是什么范围?
2、抖频功能改如何设置参数?
3、最大负载5A,RSENSE = 10 mΩ,CDC改如何设置,
这二个电压分别表述什么意思。
4、电感4.7uh@7A,负载电流最大5A,该如何设置ILIM的电阻。
谢谢

HI:
1. To reduce the switching power loss in high power conditions, it is recommended to set the switching frequency below 500 kHz. If a system requires higher switching frequency above 500 kHz, it is recommended to set the lower switch current limit for better thermal performance.
2. 参数设置,可以借助TI的在线仿真webench(见芯片官网)
