Part Number: UC1875-SP Hi Team,
My customer is looking for the specific ThetaJC from the junction to case BOTTOM value for the 5962-9455501VRA device. The only listed thetaJC on the datasheet is the top value. Can you share with us this information?
Regards…
Part Number: UC1875-SP I had a question about the below diagram that is part of the UC1875-SP spec. (Figure 1 page 5)
The diagram shows duty factor (DF) to be t/T. This would always be 50% for all F. The actual DF = tx/T, where tx covers the same time…
Part Number: UC1875 Hi TI
I am using UC1875 PWM IC for full bridge converter. I am not getting pulses and Vref is coming 5.9V ( it should be 5V). I am getting good slope as per datasheet. I have tried multiple ICs but everytime I get 5.9V Vref.
When…
Part Number: UC1875 I am designing a power supply system for a spacecraft application. My program requires us to complete a detailed part stress analysis for the control circuit of this supply which uses a UC1875. My analysis must show compliance with…
Part Number: UC1875-SP I see that the UC1875-SP has an ELDERS report, but I have a customer asking the following questions regarding the UC1875-SP:
Do you have any latch up test results for the UC1875-SP? This is for radiation environment, specifically…
Part Number: UC1875 Hello,
I see that the UC1875 is QML Class V but I have an interest in using this in an application up to TID of 100 krad and must also survive ELDRs. I see from the datasheet that the part is only guaranteed for 50 krad. Is it possible…
Hi Carl,
As this is a bipolar process design and the operating frequency is in kHz and we are concerned about the dead time thus TID radiation would not be a major concern that would effect the dead time. If you measure dead time and then select…
Part Number: UC1875-SP Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hello,
My customer has a request.

Could you make the P-SPICE Model for UC1875-SP ?
Best Regards,

Other Parts Discussed in Thread: UC1875 For the UC1875, will any damage to the device occur if the CLOCKSYNC pin is shorted to ground? If the CLOCKSYNC is not used, i.e. the controller is set to free-run, how should the CLOCKSYNC pin be terminated?
Other Parts Discussed in Thread: UC1875 I did a circuit using uc1875. I am getting ramp waveform only 150 mVpp with 0.4V offset. Let me please know how the actual ramp wave from look like with peak values and details of R slope and ramp capacitor. Whether…
