TPS54201: Maximum PWM signal frequency

Kazuhiko Hirano

Part Number: TPS54201

Hello,

The datasheet says “To minimize this ripple, the suggested PWM signal frequency is 10 kHz or higher, such as 50 kHz.”.
What is the maximum PWM signal frequency that can be used?

Best regards,

Hi ,

There is a LC filter after PWM signal in device to get average output current instruction， which means there is no clear maximum PWM frequency.
