Hi Harish, You again suggest that I "change the transformer inductance" however, the only way to change the transformer inductance is to change the transformer itself. As I mentioned before, that isn't a viable solution. The UCC28700 is supposed…
Part Number: PMP10200 Other Parts Discussed in Thread: UCC28700 , Tool/software: Hello-
I'm looking to develop a high power (10's kW) DC/DC converter to drive a heater load. PMP10200 outlines an application of the UCC28700 for at least the core of…
Part Number: UCC28700-Q1 Tool/software: Hello,
We are using TI UCC28700-Q1 to design a flyback power supply. A problem was found during test, please help analyze the possible reason:
Design parameters:
Input voltage :60-500Vdc, Output voltage: Second1…
Part Number: UCC28700 Tool/software: We are seeing some devices in production that are utilizing the UCC28700 to convert 120VAC to 5V occasionally do a UVLO reset. We have only seen this on a few devices but have confirmed:
Temperature when it is occurring…
Part Number: UCC28700 Other Parts Discussed in Thread: LM5185 , , LM5023 , UCC28600 Tool/software: Hi,
We are trying to develop a 3kW converter quasi resonant with input 12Vdc and output 3kV dc.
The power of this converter should be 3.5W and will work…
Part Number: UCC28700 Other Parts Discussed in Thread: LM5020 Hi,
I am looking for a PWM controller similar to that of UCC28700 / LM5020 but with <50kHz switching frequency.
Reason : My operating input is 50V-1500V and so the minimum ON time of the primary…
Hi Harish,
Thanks for your response.
Now my project is working well. The only difficulty is to start up the power supply with a low input voltage equal to 60 V. Moreover, the output voltage tends to oscilate when I turn-off the load. Apart from that, the…
Part Number: UCC28700-Q1 Other Parts Discussed in Thread: UCC28700
The question I have regarding UCC28700 flyback controller is what is the TI recommended way to shutdown the controller UCC28700, when input dc VBLK goes below a certain level.
We can…
