FEATURES High efficiency: Size: 90% @ 3.3V/ 20A 58.4mmx22.8mmx10.0mm (2.30”x0.90”x0.39”) Industry standard pin out Fixed frequency operation Input UVLO, Output OTP, OCP, OVP Basic insulation 2250V isolation No minimum load required ISO 9001, TL 9000, ISO 14001, QS 9000, OHSAS 18001 certified manufacturing facility UL/cUL 60950 (US & Canada) recognized, and TUV (EN60950) certified CE mark meets 73/23/EEC and 93/68/EEC directive Delphi Series E24SR, 66W Eighth Brick Family DC/DC Power Modules: 24V in, 3.3V/20A out www.DataSheet4U.com OPTIONS The Delphi Series E24SR Eighth Brick, 24V input, single output, isolated DC/DC converters are the latest offering from a world leader in power systems technology and manufacturing ― Delta Electronics, Inc. This product family is available in either a through-hole or surface-mounted package and provides up to 66 watts of power or 20A of output current (3.3V and below) in an industry standard footprint and pinout. The E24SR converter operates from an input voltage of 18V to 36V and is available in output voltages from 3.3V to 12V. Efficiency for the 3.3V output is 90% at 20A full load. With creative design technology and optimization of component placement, these converters possess outstanding electrical and thermal performance, as well as extremely high reliability under highly stressful operating conditions. All models are fully protected from abnormal input/output voltage, current, and temperature conditions. The Delphi Series converters meet all safety requirements with basic insulation.
