Other Parts Discussed in Thread: UC3846, , UC2846, UC1856-SP, UC1846, UC1843A-SP, UC1843B-SP, UC1843, UC1856
Hello, and before I go on, Thank you for considering the following questions:
- Are the UC1846-SP and UC1856-SP fabricated using any special process for radiation hardening such as SOI. Aside from the obvious packaging differences, is the Die the same as the standard versions UC2846, UC3846 etc? i.e. same Mask, same fabrication process. If not the same, then please could you explain the differences.
- Are the UC1846-SP and UC1856-SP recommended for new designs; how long does TI intend to continue manufacture? I can see the status is Active, but I’m looking for an answer in Years if possible.
- Based on the radiation performance, would TI recommend using either of these devices with a 28V Input, 5V, 1A Output?
- For missions that are short duration, where SEE are the main concern. Do you have any information/experience with SEE (latch-up and destructive effects) at different input voltages up to the maximum rated voltage of 40V? Is there a de-rated input voltage for a given radiation performance?
- Does TI plan to develop any new Radiation Tolerant step-down regulators or PWM controllers that may be a better alternative to the UC1846-SP / UC1856-SP
I look forward to your response.
