Short pin lengths available This product family is available in either a through-hole or External Synchronization surface-mounted package and provides up to 120 watts of power or Output OVP latch mode 50A of output current (1.2V and below) in an industry standard footprint Heat spreader and pinout. The E48SH converter operates from an input voltage of 36V to 75V and is available in output voltages from 1.0V to 15V. Efficiency is 90% for 1.8V output at 40A full load. With creative design technology and optimization of component placement, these converters possess outstanding electrical and thermal performance, as well as APPLICATIONS extremely high reliability under highly stressful operating conditions. All Telecom/DataCom models are fully protected from abnormal input/output voltage, current, Wireless Networks and temperature conditions. The Delphi Series converters meet all Optical Network Equipment safety requirements with basic insulation.
