Part Number: UCC3895 Other Parts Discussed in Thread: UCC1895 , UCC2895 Hi,
In the datasheet, UCC3895 has operating temperature of 0 to 70C.
1. operating junction temperature is -55 to 125C. Why is gap from operating to operating junction temperature bigger…
Hi Collin,
Just wondering if you were able to look at this at all? I have continued to play around with the last circuit you sent, but I have had no luck.
Also, I would like to simulate the UCC1895/2895/3895 in LTSPICE. Can you send me the unencrypted…
We run board simulation with Ansys Simplorer. However the simulation doesn't run due to your Pspice model issue. I preprare for the detail as attached PPT. We need unencrypted Pspice model. If you need NDA, please provide a format so that I can proceed…

question:
we are using the older UCC1895 & it has the single core triple 1:1:1 gate drive xmfr for A-B & another for C-D legs. Can this still be used with UCC28950?
question:
is this sync freq requirements different from UCC1895? you say 1.8xfs, which freq will that be? Output inductor freq is 2xdiagonal switch freq. If inductor freq is 600 kHz, will this mean sync freq needs to be 1.08 meghz?
this sounds a bit off…
Part Number: UCC2895 Hi,
The current discharge of RAMP circuit is specified on page 5 of the datasheet: I_R(sink)=12mA min and 19mA typical.
Which parameter influence the dispersion of this discharging current?
Moreover, in case CT and RAMP are not connected…
