Is it possible to use UCC28180 for switching 10 kHz ? I see datasheet only 18 kHz min.

Hi Suriya Sratt

Ti recommends UCC28180 controllers be used at 18kHZ-250KHz, at this frequency range, the precison of the frequency is undercontrolled and can follow the datatsheet.

UCC28070A can support 10kHz but is two phase interleaved controller.
