    Hi, We are not familiar with INA180A1. Please create a new thread to ask support related to INA180A1. Without waveforms, we cannot support UCC28C50 as we do not know where is likely wrong so not able to provide suggestions.

    Hi Flavio. 1. I do not recommend connecting directly VIN voltage to VDD pin. VDD max voltage it can handle is 30V (see below), which is the same minimum voltage in your case. Rstart should be designed at the lowest line voltage (30V) conditions and to…

    Thanks for your answer. Is it also possibte to get a negative DC DC output voltage at the output and to make a feedback control loop by measuring the output voltage? And do you think low ripple could be possible with the UCC28C50? Are there any application…
