Part Number: UCC2805-Q1 hello? My name is HL mando researcher Seongtaek Oh. Currently, we are using UCC2805-Q1 as a Flyback SMPS power device in our internal project. Here, the output of the SMPS (= used as gate driver power) requires more load. As a…
Part Number: UCC2803-Q1 Other Parts Discussed in Thread: UC3842 Hi Team,
UCC2803-Q1 should be able to do boost, but I see all designs including application in datasheet/ webench/ reference designs are all isolated flyback solution. So I'd like to check…
Part Number: UCC2803-Q1 Hi team,
A few questions regarding the functionality of the UCC2803-Q1's current sensing pin and Section 9.3.11. Please see below!
Is the voltage divider providing a DC offset to the current sense voltage?
To design this, need…
Part Number: UCC2803-Q1 Hello,
We have designed an isolated flyback converter based on UCC2803 based on the inputs from WEBench.
However, we are facing a lot of issues in bringing up the hardware. I am attaching our design here. The problem is that I am…

Part Number: UCC2803-Q1 Other Parts Discussed in Thread: UCC2803 Team,
What alternative would you recommend for NJW4140 https://www.njr.com/semicon/PDF/NJW4140_E.pdf
UCC2803 may work, but customer prefers to have the EN pin.
Thanks!
