ADUM3190 in UL certified AC-DC Converter

Hi All,

When I introduced ADUM3190 to AC-DC Converter design customer, he said that the ADUM3190 can be used in AC-DC Converter unit to be certified by CSA and VDE, but couldn't be used in the unit to be certified by UL.

Is this true? He said that only opto-coupler be used for the UL.

How can I promote ADI isolator to this customer?

Best Regards,

Ricky

    Ricky: The ADuM3190 has been certified by UL for single protection as a non-optical isolator, the same as many of our other digital isolators - see attached certification.  If they are looking for UL double protection, this is not typically provided by digital isolators.  But, we do provide the equivalent of double protection called reinforced insulation, which is provided in the wide body package in the ADuM4190 and is certified by VDE and CSA.  Most line powered applications can use the VDE and CSA reinforced insulation.
