Efficiencies greater than 93% over the entire input range are typical. Additional features include higher ambient operating temperatures, reduced airflow requirements, excellent regulation and transient response characteristics. Single board package with industry standard footprint. Designed for through hole mounting. Applications These units are ideally suited for telecommunications mobile/optical switches, high capacity network routers, systems requiring distributed power architecture and high isolation.
