Part Number: UCC28750 Tool/software: Hello, I have designed a power supply using UCC287506 to be operated on 100kHz, 12 watt output power. I am facing an issue during startup at full load. My observation is that during startup the controller is switching…
Hi Simon,
Try reducing the Current sense value well below the calculated resistor value say 40 to 50%. You might be able to achieve the over power application.

Part Number: UCC28750 Hello,
We're working with the UCC287505 in 2 separate designs. The first is AC to DC solution and we need an opto coupler.
However the other design is low voltage DC to DC flyback and we would like to remove the opto.
Is it possible…

We're working on a UCC287505 flyback design.
One version of the solution is AC input and we need to isolate the secondary.
however a different version is using…
