PKN4000I Datasheet | Ericsson Microelectronics

PKN 4000 I 50 W DC/ DC power module 48 V input series - Regulated single and dual outputs - Efficiency >90% (3.3V) from 30% to full load - Low profile 8.5 mm .. (0.335 in.) - 1,500 Vdc isolation voltage - MTBF >200 years at +75°C case temperature - Full power up to +80°C ambient at 1 m/s airflow - plete, no extra filters or heatsinks required The PKN 4000 I series of DC/DC power modules are intended to be used as distributed power sources in decentralized 48/60 V DC power systems. The PKN series use a ceramic substrate with thickfilm technology and a high degree of silicon integration. That together with the electrical design using synchronous rectification gives good thermal management, high reliability and high efficiency. The high efficiency, makes it possible to operate over a wide temperature range without a heatsink. At forced convection cooling >200 lfm (1 m/s), the PKN units can deliver full power up to +80°C ambient temperature. The high reliability and the low profile of the PKN series makes them particularly suited for Information Technology and Tele (IT&T) applications with board spacing down to 15 mm (0.6 in.). These products are manufactured using highly automated manufacturing lines with a world-class quality mitment and a five-year warranty. Ericsson Microelectronics AB has been an ISO 9001 certified supplier since 1991. For a plete product program please reference the back...
