Hi Experts,
As we know, TPS568230 use DCAP3 method. In this way, Ton=k*Vout/Vin. But how does our device detect Vout? It seems there is no pin directly connected to Vout.
Look forward your kindly reply. Thanks a lot.
Best regards!

Hi Wilson,
Inside the device, we have several R-C filter with large time constant on SW pin. The average voltage of SW can be regarded as the Vout.
Any further question, please let us know. Thanks!
