Part Number: UCC28C53 I am using UCC28C53 in my flyback design and am seeing spikes on the VREF pin when a load is applied.
This waveform is DC with a 2A load applied to the output:
It seems the VREF pin sees spikes above 7V when the MOSFET switches…
Part Number: UCC28C53-Q1 Other Parts Discussed in Thread: UCC28C56H Tool/software: Dear Team ,
in the EVB of the UCC28C56H Q1, we can see the Short circuit to Ground waveforms. I have some qtns on that pls reply :
1. Does the UCC28Cxx family supports…
Part Number: UCC28C53 I have a design using UCC28C53DR with the following parameters:
Vin = 85-265VAC
Vout = 24V/4A
fsw = 100kHz
When applying a 1.5A load to the output, I see this waveform on the Gate of the MOSFET.
The gate is clearly not…
Part Number: UCC28C53-Q1 Dear Team,
I am designing the flyback the with Vin 67 to 180rms, and Vo 12V, 2A. I have gone thru the Webench schematic, observed that 18V zener connected across VDD pin for protecting the IC.
the D12 is VZ 18V @ IZT 7mA…
Part Number: UCC28C53 Hi team,
Could you please kindly help check if we have device with under voltage protection?
Our UCC28C5x only have UVLO.
Thanks,
Brian
