Unable to observe PWM output

Category: Hardware
Product Number: ADN8835

Hi Team,

For the TEC IC ADN8835, the pin number 20 & 21 are the SW outputs which are supposed to be obtained as PWM wave. But, the same wasn't observed when probed. DC voltage is observed, not the PWM.

Can you let me know what might be the issue.
