Tool/software:

Hi,

Customer would like to utilize SW of TPS548A29 to provide sync to TPS543C20A.

Is it available for synchronization of 2 DCDC(TPS548A29 and TPS543C20A)?

Because TPS548A29 is DCAP-3, I think there is stability of switching frequency during transient or light load.

Please check this and if there is another solution, please recommend it.

Thanks.

Hi David,

Depending on the load of TPS548A29, there may be some slight increase/decrease in the SW frequency during load transient.

I would recommend using a fixed frequency device such as TPS543620 or TPS543B22 depending on the needs of the buck converter.

Best,

Ryan
