THVD8000: Frequency Hopping with F_SET Pin

Antonio Fadhel

Part Number: THVD8000

Hi Team,

My customer is evaluating the THVD8000 but they need to implement "frequency hopping" to avoid noise from a motor in the system. Is it possible to change frequencies with a DAC at the F_SET pin?

Thanks,

Antonio

Antonio,

The device has integrated some level of spectrum spreading.

If it's not enough, surely you can use a DAC to control a variable current source at the F_SET pin. The frequency varies with current load.
