Part Number: UCC28C56L Tool/software: I have designed a flyback circuit to convert 100V to 12V using UCC28C56L. As per the reference design from Webench designer the Input supply is stepping down to 18V (VDD Pin) to turn on the IC. However the IC is not…
Part Number: UCC28C56L Tool/software: I tried capturing the voltage across the MOSFET using trigger. I could only get the waveforms during the start of the converter. The waveforms did not show any voltage spike across the MOSFET which could damage the…
Part Number: UCC28C56L Tool/software: I have designed a flyback circuit with UCC28C56L by taking the reference from the datasheet, Webench designer. When I connected the board to the power supply I noticed that the constant input voltage which is supposed…

Please find the attached schematic of Flyback Converter using IC UCC28C56LQ1. We are trying to test it with 100 V input supply to get the 12 V output. However, MOSFET Q1, resistor…
Part Number: UCC28C56L-Q1 Tool/software: In the datasheet there is no mentioning of the loss calculation of the flyback transformer. Please assist me in finding a suitable calculation method for the DCM mode flyback Transformer Loss calculation. Thank…
Part Number: UCC28C56L-Q1 Tool/software: I am working with the UCC28C56L-Q1 flyback controller for a power supply design and have encountered a couple of issues regarding the startup and operational mode. 1. CCM vs DCM Operation: I used the Webench tool…
