Note 1:

The iW1830-EVAL1 has been designed to meet UL1310 (up to 120VAC) with the exception of the common mode choke

L4 (see Note 2) and EN60335-1:2012, however individual boards have not been tested or verified to these standards.

Note 2:

The iW1830-EVAL1 uses a common mode choke which is intended for 5V/3A designs that are used as part of circuits

in white goods. Alternative UL-1310 compliant parts should be used if this design is used for a standalone 5V/3A power

unit.
