Part Number: UC1825A-SP Other Parts Discussed in Thread: UC1825-SP , UC1825B-SP The datasheet of UC1825A-SP said that “The UC1825A-SP outputs are alternately controlled”, so that duty cycle varies “from 0 to less than 50%”. However, in Fig. 15 of the datasheet…
Part Number: UC1825A-SP If the Error Amp Out pin (Pin 3) is clamped at 2.5V as a secondary protection circuit beside the normal current limit (Pin 9). When the converter going into current limit, will the Clamp voltage at E/A OUT will override the Current…
Part Number: UC1825A-SP Hello,
Question about the UVLO threshold for the UC1825A-SP. The spec is about 9.2V nominal. What is the coefficient of this threshold over temperature ? Is it increase or decrease with Hot temperature ?
Best Regards,

Part Number: UC1825A-SP Hi Team, We have a customer inquiry on how much Voh and Vol vary with temperature to help calculate radiation end points. Please let us know if you have other questions with the customer. Thanks! Jonathan
Part Number: UC1825A-SP I am looking for the tolerance variations (initial tolerance , temperature, aging, radiation) of the 1.25 V internal which connects to the RAMP pin. Beside the 1.25V could impact the current limit, is there any internal parameters…
Part Number: UC1825A-SP Other Parts Discussed in Thread: TINA-TI , UC1825A , Tool/software: TINA-TI or Spice Models Is there any device accurate model of UC1825A or UC1825A-SP supported in TINA-TI simulation tool? Don't see it in the standard library. If…
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
