D12S300-1 C

FEATURES High Efficiency: 94% 12Vin, 5.0V/60A out Wide input range: 4.5V~13.8V Output voltage programmable from 0.6Vdc to 5.0Vdc via external resistors No minimum load required Fixed frequency operation Input UVLO, output OCP, OVP. Remote On/Off (Positive logic) Power Good Function RoHs completed ISO 9001, TL 9000, ISO 14001, QS9000, OHSAS18001 certified manufacturing facility Delphi D12S300-1 Non-Isolated Point of Load DC/DC Modules: 4.5V~13.8Vin, 0.6V~5.0Vout, 60A OPTIONS The D12S300-1 series, 4.5~13.8V input, single output, non-isolated point of load DC/DC converters are the latest offering from a world leader in power systems technology and manufacturing -- Delta Electronics, Inc. The D12S300-1 series product provides up to 60A and the output can be resistor trimmed from 0.6Vdc to 5.0Vdc. It provides a very cost effective point of load solution. 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. The D12S300-1 series is a voltage mode controlled Buck topology. The output can be trimmed in the range of 0.6Vdc to 5.0Vdc by an external APPLICATIONS resistor from Trim pin to Ground. The converter can be turned ON/OFF Telecom/DataCom by remote control with positive on/off (ENABLE pin) logic. The Distributed power architectures converter DC output is disabled when the signal is driven low. When Servers and workstations LAN/WAN applications this pin is floating the module will turn on. The converter can protect Data processing applications itself by entering hiccup mode against over current and short circuit condition. Also, the converter will shut down when an over voltage protection is detected.
