The current in the inductor cannot change suddenly. (After the voltage across the inductor is removed, the current will not disappear immediately, thus generating a reaction potential)Inductor is an e...
Given that the output voltage is 12V and the maximum input voltage is 42V, find the value of L1.
According to BUCK MODE, L1=（12*(42-12））/（42*300000*1.2）
The document says L1=28UH, but no matter how I ...
