Part Number: UCC3895 Dears:
When UCC3895 is used as the full bridge control, when the single bus AC voltage exceeds 380V, the duty cycle of OUTC OUTD output will be unbalanced and cannot be maintained at 50% duty cycle, resulting in high current peaks…
Part Number: UCC3895 Other Parts Discussed in Thread: UCC2895 Hello
for a new design I'd like to drive the SYNC pin of UCC 2895 with an external clock signal. Reading the data sheet I don't understand what I have to do with pins Rt and Ct.
Can…

Part Number: UCC3895 Other Parts Discussed in Thread: UCC2895 , UCC28950 , UCD3138 Dear Sir or Madam, I am currently using UCC3895 for Peak Current Mode control PSFB PWM generator.
I read the datasheet and I set the current sensor value of 0-2V, the frequency…
Hello,
I reviewed your schematic and waveforms.
I reviewed your schematic and the design seems to be setup for some kind of half bridge and not a full bridge. The UCC3895 is not designed for this configuration. This is most likely what is causing your…
Hello, I learned from the data sheet of ucc3895 that ucc3895 can work in current mode or voltage mode. In current mode, the RAMP pin is connected to the CS pin. And in voltage mode, The RAMP pin is connected to the signal at CT. I want ucc3895 to work in voltage…
Part Number: UCC3895 Other Parts Discussed in Thread: PMP9622 , UCC28950 Hi Team,
i have designed a power supply using UCC3895 and its working fine without feedback but as soon as i connect the feedback circuit to the IC it doesn't work, So i am attaching…
Part Number: UCC3895 Other Parts Discussed in Thread: UCC39002 , UCC29002 , UCC2895 Hi team , 1- Can we adjust the output voltage by change the uC duty cycle Like this figure below? the uC generates PWM signals and the signals are filtered ( converted ) to…
Part Number: UCC3895 Other Parts Discussed in Thread: UCC2895 Hi,
I read the SLUA501 application note "UCC2895 Layout and Grounding Recommendations". Can I put the "quite ground plane" and "power grpund plane" in the same PCB layer or I have to put them…
