Part Number: UCC28704 Tool/software: Hello,
Is it possible to get a design for the attached schematic. We will work with GCI regarding the transformer.
Thank you,

Part Number: UCC28704 Hello,
I would like to know if you'll correct the Pspice Model of the component to avoid a shut down after 2ms of running.
I thank you for your attention.

Hi,
I am using the output of a flyback for gate circuits and a fan. With a very low frequency (600 Hz), the flyback enters CCM. I have Schottky diodes for the secondary diode. Do I need to add snubbers to the Schottky diode?
Part Number: UCC28704 Hello, I have designed this UCC28704 AC/DC flyback converter circuit. I am wondering if the return path of the bridge rectifier is correct?. Also, can you help me find a compliant PN for a transformer to be used with the Converter…
Part Number: UCC28704 Dears,
Customer feedback that when they use UCC28704 flyback power supply,Output Volatge is 15V/1.2A,when the load is light,the output is normal and when the load is heavy,the output is unstable.
Pls kindly help to check the schematic…
Part Number: UCC28704 Hello Team,
As I read in the data sheet, the CS pin is typ. 356mV with constant current regulation.
During a measurement I noticed that the voltage is up to 750mV with constant current regulation, as you can see in the following…
Part Number: UCC28704 Hi,
We are producing the custom board(28704) as follows.
R116, R138, FET(Q14), R89, R137 are burned in a few boards.
we are using the 15V_aux power for the ucc 256303 and using the 15V_ISO power for the UCC24612-2
can you help me…
Part Number: UCC28704 Any one can server for the question, thanks.
What maximum power level can UCC28704 support?
What is the minimum operation voltage of VCC? Is 8.5?
Enables <30-mW No-Load Input Power: Are there any conditions for this No-Load Input…
Part Number: UCC28704 Hi experts,
The customer has came across the problem that the UCC28704 can't work normally in their flyback circuit.
Circuit parameter and test condition:
1. Vin_flyback= 24V, Vout_flyback = 24V.
2. Flyback circuit are…
Hello,
6 to 1 is quite a large variation in input voltage. You might be better designing with a DCM flyback converter that uses variable frequency. You can do this with a primary side regulated UCC28704 or a UCC28742.
