I have the following observations from the limited details on the video.
1. Assuming the output power is 780W (from scope) and Fsw 50Khz for universal input range, the inductor of 180uH seems very less. ( calculations show it should be atleast…
Part Number: UCC28180 Dear sir,
I am USING UCC28180DR. when switching the mosf et Gate to source voltage generate the spike. when I increase the load similiarly, spike also increase. please help me to resolve that issue.
Part Number: UCC28180 Hello.
I’m designing power supply system using UCC28180.
I want to know the time to automatically restart in the input voltage instantaneous stop test.
The VCC voltage is fixed at 15.0V .
I have attached a calculation sheet.

I have designed a 2.5kW PFC using UCC28180.
While testing.it, on giving isolated 230VAC input(from mains without auto transformer). The output ceramic capacitors exploded and the test failed.
We followed the test procedure…
Part Number: UCC28180 Hi Team,
I have used UCC28180 PFC Boost IC for the 700W output power. Output Voltage is 390VDC.
I am facing issue during the step load. When I am applying 700W output load with 115VAC input supply then boost output goes to below…
Part Number: UCC28180 Hello,
I am trying to test a control card with UCC28180, but before testing it with the High Power plant/ baseboard, I want to test the controller card individually to check if it gives desired gate output.
For 65kHz operation,
