UCC5870-Q1: FPWM Minimum Frequency

Ray Vincent Aranzaso

Part Number: UCC5870-Q1

Hi,

Good Day.

On DS page 3, the IN+ pin description says that it's restricted to 1kHz to 50kHz. However, on DS page 7, the fPWM spec has no minimum frequency for IN+ and IN- pins.

So, is there a minimum frequency for the IN pins? If so, what happens if we go below that frequency spec.

Please advise. Thank you very much.

Best Regards,

Ray Vincent

    Hello Ray,

    Thanks for your interest. 

    Please follow the recommended operating conditions, which don't specify a minimum frequency. This driver has no minimum frequency. 

    I will make a note to clarify the pin description in the datasheet.
