I INCREASED THE DEAD TIME BETWEEN TWO MOSFET STILL AFTER 20 SEC MY OUTPUT VOLTAGE IS DIPPING(i.e DECREASING) AT 652 OUTPUT VOLTAGE AND MOSFET THERMALS ARE…
Part Number: UCC28083 Other Parts Discussed in Thread: UCC28084 , UCC28086 Hello guys,
One of my customers is looking for any evaluation board for UCC28083 (or UCC28084/85/86) to evaluate the device for their new products.
Do you have any evaluation…
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…

Dear Ben,
After testing with installing a decoupling cap from the VDD pin to ground and,the issue persists . The ucc28083 cann't satrt up when Vin is changed back to 60V from 80V .
There has no a significant difference between the good and the NG…
