... Nominal line voltage, no-load/full-load conditions. Please refer to the Part Number Structure for additional options when ordering. The operating input voltage is 10.2V to 13.8V. However, 10.8VIN is required for the DC/DC to properly start up under all line, load and temperature conditions. The 10.8V potential must be maintained across the inputs until the output is up and regulating ...

... Control) should be referenced to Common (specifically pin 1). I/O Filtering and Noise Reduction All models in the HEN D12 Series are tested and specified with external 33μF tantalum input and output capacitors. These capacitors are necessary to accommodate our test equipment and may not be required to achieve desired performance in your application ...

... Many DC/DC's using synchronous rectification suffer from Output Reverse Conduction. If those devices have a voltage applied across their output before a voltage is applied to their input (this typically occurs when another power supply starts before them in a power-sequenced application), they will either fail to start or self destruct. In both cases, the cause is the " ...

... DATEL power supplies and add a safety margin. Please study the Derating Curves to understand the increased thermal capacity available when a heatsink is installed. DATEL will supply our custom-designed heatsinks already installed. If preferred, users may also purchase the heatsink assembly separately. If so, please carefully follow the installation instructions below to avoid damage to the DC/DC converter ...

... Orientation: When loaded into JEDEC trays, these converters are all oriented in the same direction. See the diagram below. For the LEN and HEN series, a notch is placed on the top of the case (on the removal tabs) to indicate the pin 1 position. You should visually inspect the tray to be sure of this orientation ...
