Hi,

Could your tell me about TPS25942 UL2367?
Can you meet an LPS examination of UL60950/EN60950 if customer used the part(TPS25942) which acquired UL2367?
Customer is trying to clear the LPS test by adopting a TPS25942.

Hello Yusuke,

As I mentioned earlier that TPS25942 is UL 2367 Recognized.

it also meets the UL60950/EN6065 Safe during Single Point Failure , Open/Short ILIM detection requirements.

I am not sure what additional information you are looking for.

Please let me know your specific question.

Best Regards

Hi Dinesh-san,

Thank you for your response.
LPS(Limited Power Source) is UL60950-1 category test.
I listed in the following related sites.
http://www.ul.com/global/documents/offerings/industries/hightech/informationtechnology/new/60950-1_2ndEd_Analysis_rev_May%2021%202010.pdf

Customers want to pass the tests(required for the fuse and poly switch).
However customers and I are not familiar with UL standard.
Could you tell me if you can correspond to LPS in UL2367.

Hi Dinesh-san,

I will describe the additional information.
Customers want a certification of IEC60950-1-am2.
