6 / 14 page Advance Data Sheet November 17, 2011 40A Analog Mega DLynxTM: Non-isolated DC-DC Power Module 4.5 – 14.4Vdc input; 0.6Vdc to 2Vdc output; 40A output current LINEAGE POWER 6 Design Considerations Input Filtering The 40A Analog Mega DLynx TM module should be connected to a low ac-impedance source. A highly inductive source can affect the stability of the module. An input capacitance must be placed directly adjacent to the input pin of the module, to minimize input ripple voltage and ensure module stability. To minimize input voltage ripple, ceramic capacitors are recommended at the input of the module. Figure 1 shows the input ripple voltage for various output voltages at 40A of load current with TBD µF or TBD µF ceramic capacitors and an input of 12V. TBD Figure 1. Input ripple voltage for various output voltages with TBD µF or TBD µF ceramic capacitors at the input (40A load). Input voltage is 12V. Output Filtering These modules are designed for low output ripple voltage and will meet the maximum output ripple specification with 0.1 µF ceramic and TBD µF ceramic capacitors at the output of the module. However, additional output filtering may be required by the system designer for a number of reasons. First, there may be a need to further reduce the output ripple and noise of the module. Second, the dynamic response characteristics may need to be customized to a particular load step change. To reduce the output ripple and improve the dynamic response to a step load change, additional capacitance at the output can be used. Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response of the module. Figure 2 provides output ripple information for different external capacitance values at various Vo and a full load current of 40A. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified in the electrical specification table. Optimal performance of the module can be achieved by using the Tunable Loop TM feature described later in this data sheet. TBD Figure 2. Output ripple voltage for various output voltages with external TBD ceramic capacitors at the output (40A load). Input voltage is 12V. Safety Considerations For safety agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards, i.e., UL 60950-1 2nd, CSA C22.2 No. 60950-1-07, DIN EN 60950-1:2006 + A11 (VDE0805 Teil 1 + A11):2009-11; EN 60950-1:2006 + A11:2009- 03. For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a fast- acting fuse with a maximum rating of TBD A in the positive input lead . |
