Hi Lin,

Without understand more about what you are trying to do here...It's hard to comment on what is wrong. Is there a reason you are PWM'ing the IADJ at such high frequency? If you want to PWM the output then UDIM_A is where you want to drive the PWM'ing signal. What switching frequency are you trying to set the regulator to?

Thanks Tuan
