Part Number: UCC28083 On the data sheet for the UCC28083, July 2009 edition there are two partial schematics which highlight a RC network that drives the current sense input. In one schematic, on page 6, in Figure 1, the filter capacitor is shown as a…
Part Number: UCC28083 Hello Guys,
Good day.
Our customer wants clarification on the maximum input voltage of UCC28083 on Webench. Why does Webench limit Vin to 70V? When a separate Vcc of 12V is used, the only electrical limit on Vin is the voltage rating…
