UC1901-SP: SEL info

Part Number: UC1901-SP
Other Parts Discussed in Thread: TIDA-070002, UC1843A-SP,

Team, 

My immediate need is to come up with an architecture for a HARD Isolated House-Keeping power supply (~50W).

Similar to TIDA-070002

The PWM Controller’s (UC1843A-SP) SEL/SEB/SEGR has immunity up to 75 MeV.cm2/mg which is good news.

 

The Space Catalog states that the SEL of  Isolated Magnetic feed back device (UC1901-SP)  is Bipolar.

Bipolar does not tell me much. Is it Bipolar on SOI? I guess what I want to know is does the UC1901-SP get latch up? If yes, at what SEL level?
