UCC28063A: UCC28063 UL certificate

Hello Hsu cheng,
Do you know which UL standard you are looking for ?
TI parts are used in an end product that it tested by UL to meet a particular standard such as UL1310 or UL60950
UL will require parts like optocouplers or Y capacitor to have approval for isolation
Some of the TI isolation drivers have a UL certificate for example but not PWM regulators such as the UCC28063A.
If the end product is approved by UL then it is granted an approval number to the tested standard.
UCC28063A meets the requirements of UL94V0 for flammability.
Regards
John
