TPS552882-Q1: 使用,请教几个问题

Part Number: TPS552882-Q1


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

        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)
