Part Number: TPS543C20

Dear Sir

If I set the TPS543C20 to stand-alone mode, does the SYNC PIN output a PWM signal?

below is my setting for you reference.

Hi Allen,
In the stand-alone-mode, the sync pin outputs clock signal.
Thanks,

Hi Amnat

Thank you for your reply,

Another question, If I set TPS543C20 at Slave mode, the switching frequency of TPS543C20 will follow the input frequency of SYNC pin (from FPGA)?

and I need provide SYNC signal before TPS543C20 enable, am I right?

Hi Allen,

In the stand alone mode with the external clock into the SYNC pin, the TPS543C20 will support the frequency from 200kHz to 2 MHz. The TPS543C20 will follow the input frequency of the SYNC pin. Yes, the SYNC signal needs to be available before the TPS543C20 enables.

Thanks,

Amnat
