Bourns® Power Supply Component Guide
Whether external or internal, forward or flyback, each type of SMPS is subject to regulatory requirements. A power supply for a telecom installation must potentially comply with Telcordia or ITU requirements, depending on the target region and application. In the consumer or industrial sector, IEC, UL and CSA standards govern the equipment level. Bourns can help and advise which protection scheme may be best to comply with requirements.
