FEATURES High Efficiency: 94% 12Vin, 5.0V/80A out Wide input range: 10.8V~13.2V Output voltage programmable from 0.8375Vdc to 5.0Vdc via external resistors No minimum load required Fixed frequency operation Input UVLO, output OCP, OVP, OTP. Remote On/Off (Positive logic) Power Good Function RoHS 6/6 compliant ISO 9001, TL 9000, ISO 14001, QS9000, OHSAS18001 certified manufacturing facility UL/cUL 60950 (US & Canada) Recognized Delphi D12S400 Non-Isolated Point of Load DC/DC Modules: 10.8~13.2Vin, 0.8375~5.0V/ 80A output The D12S400, 10.8~13.2V wide input, single output, non-isolated point of load DC/DC converter is the latest offering from a world leader in power systems technology and manufacturing -- Delta Electronics, Inc. The D12S400 and ND/NE product families are part of the second generation, non-isolated point-of-load DC/DC power modules which cut the module size by almost 50% in most of the cases compared to the first generation NC series POL modules for networking and data communication applications. D12S400 product provides up to 80A in the same form factor of the second generation 60A datacom POLs and the output can be resistor trimmed from 0.8375Vdc to 5.0Vdc. It provides a highly efficient, high power and current density and APPLICATIONS very cost effective point of load solution. With creative design technology and Telecom / DataCom optimization of component placement, these converters possess outstanding Distributed power architectures electrical and thermal performance, as well as extremely high reliability under Servers and workstations highly stressful operating conditions.
