Part Number: UC1901-SP I am using this part in an isolated FB loop for a critical voltage rail, I need to analyze end of life impact of the internal reference voltage, Is this data available?
Hey Vince,
The 9.76 kOhm was just to pull current out of the transformer as a burden resistor. I don't believe its required in the form I suggested to implement the UC1901-SP.
Thanks, Daniel
Part Number: UC1901-SP Hello,
We are using the UC1901-SP component for a space program. We saw in 5962-89441SMD that Life test of 125°C / 1000h was performed on component but no drift is given for the following parameters : Vref, Vos, Ios and Ib. …
Part Number: UC1901-SP Hi Team,
Can you please check and advise with the request below:
"
I could not find radiation resistance information for the product "5962-8944101VCA", which is the code available for the product UC1901-SP. Can you provide…
Hey JF,
On the primary side of the design the transformer is offset by half of the reference voltage in order to help bring it above the needed output voltage.
This allows it to get to the 2.5 V that is needed.
There are parts of the design that could…

Hi,
I am designing a DC-DC fly-back converter using UC1843-SP PWM controller for space application. The use of Opto-coupler is prohibited in my application hence feedback control is done with…
