Part Number: UCC28630 Other Parts Discussed in Thread: UCC28631 , UCC28704 Hi team,
My customer are currently designing with the UCC28630, but their input supply is going to be coming from a high voltage, DC battery. Due to the input, and lack of AC, do…
Part Number: UCC28630
Hello,
I'm having some issues making our SMPS to start up fully. It seems that it passes the 3 exploratory pulses and starts up and eventually latches up as time progresses.
Please see the schematic, layout and some waveforms…
Part Number: UCC28630 Other Parts Discussed in Thread: UCC28634 , UCC28631 Hi Team,
My customer is considering using UCC28630 to design Dual switch flyback, input 326Vdc~848Vdc, 3 outputs(total100W max): 12V/83W , -12V/3.6W, 5V/2.5W, expect efficiency…
Hello,
I reviewed your schematic and noticed you are not using an RCD clamp. If you are not should try adding one. The application note you have gives instructions for setting this up.
I also notice that you are not using a capacitor on the Vsense pin…
Part Number: UCC28630 Dear Teams,
My customer is looking the UCC28630EVM. They are not able to find the datasheet of L1 inductor (Renco Electronics RLTI-1099/8) from Internet., and I did the same thing while does not works. Could you share the datasheet…
Part Number: UCC28630 Other Parts Discussed in Thread: TIDA-00386 , Hi,
I am looking for a TINA simulation model of UCC28630D. I came across that component from the following link:

Best place to see what expected waveforms for UCC28630 is the EVM http://www.ti.com/tool/UCC28630EVM-572 . The user guide for this EVM has typical waveforms http://www.ti.com/lit/ug/sluuax9b/sluuax9b.pdf?ts=1590872018331 . If it does not include a specific…
You need connect all required components to UCC28630 to make it work. If you cannot see any pulses from its DRV after VDD reaches its on threshold, can you change a new UCC28630 to try? If you still cannot see DRV initial three pulses, power off your…
Part Number: UCC28630 Other Parts Discussed in Thread: UCC28704 I have a design based on the example in the datasheet, but regulated for 5v output, however I cannot get it to start as the circuit during the exploratory three pulses goes into overvoltage…
