FEATURES High efficiency: 90.5% 3.3V/20A Size: 58.4mm x 22.8mm x 8.4mm (2.30x0.90x0.33) Industry standard pin out SMT and through-hole versions Fixed frequency operation: 350KHz Input UVLO, Output OCP, OVP, OTP 1500V isolation Basic insulation No minimum load required 2:1 Input voltage range ISO 9001, TL 9000, ISO 14001, QS 9000, OHSAS 18001 certified manufacturing facility UL/cUL 60950-1 (US & Canada) recognized, TUV (EN60950-1) certified CE mark meets 73/23/EEC and 93/68/EEC directives Delphi Series E48SR, 66W Eighth Brick Family DC/DC Power Modules: 48V in, 3.3V/20A out The Delphi Series E48SR Eighth Brick, 48V input, single output, OPTIONS isolated DC/DC converters are the latest offering from a world leader in SMT or through-hole versions power systems technology and manufacturing Delta Electronics, Inc. Positive On/Off logic This product family is available in a surface mount or through-hole Short pin lengths package and provides up to 66 watts of power or 25A of output current (1.8V and below) in an industry standard footprint. With creative design technology and optimization of component placement, these converters possess outstanding electrical and thermal performances, as well as extremely high reliability under highly stressful operating conditions. All models are fully protected from abnormal input/output voltage, current, APPLICATIONS and temperature conditions. The Delphi Series converters meet all Telecom/Datacom safety requirements with basic insulation. The E48SR Eighth Brick Wireless Networks shares the same pin out as the Delphi Series Quarter Brick family. The Optical Network Equipment smaller footprint of the Eighth Brick modules allows the user to save Server and Data Storage board space for power requirements up to 66W.
