Other Parts Discussed in Thread: UC1825A do you have any design tools for UC1825a use like a spreadsheet for slope compensation, eff calcs, power diss., etc.
Raveej, I don't work for TI, I'm a user that had some of the issues you're having on a design last year. In particular, the problem of high minimum duty cycle. I worked with the TI engineer for almost 4-months before they concluded that there was no way…
Other Parts Discussed in Thread: UC1825A , UC1825 I'm using the TI UC1825AL PWM Control IC in a MIL/Hi-REL DC-DC Converter design. I'm an expert power electronics engineer, but never used the UC1825A before. The only documentation is the datasheet and an…
Hey Joe,
The UC1825B-SP is based on the UC1825-SP not the UC1825A-SP.
That's why the specification is not there for the UC1825B-SP.
Since its not tested I don't have any information on the EOL tolerances.
Thanks,
Daniel
Hi,
In our system, we must use NI pin with voltage level between 0V to 600 mV. Besides that, we are using UC1823A-SP so space products are essential for us. Therefore, some questions are:
1-) Is there same problem for NI pin in UC1825A-SP ?
2-) Are there…
