Description
ATM020A0X3-SR belongs to the Austin SuperLynx IITM SMT (surface mount technology) power module product families that are non-isolated dc-dc converters delivering up to 20A of output current with full load efficiency of 89% at 1.8V output. These modules provide a precisely regulated output voltage programmable via external resistor from 0.75Vdc to 2.0Vdc over a wide range of input voltage (V IN = 2.4 – 3.63Vdc). Austin SuperLynx IITM has a sequencing feature, EZ-SEQUENCETM that enable designers to implement simultaneous or ratiometric startup of multiple rails on board. Their open-frame construction and small footprint enable designers to develop cost- and space-efficient solutions. In addition to sequencing, standard features include remote On/Off, remote sense, programmable output voltage, over current and over temperature protection. RoHS Compliant EZ-SEQUENCETM

This power module can be used in a wide variety of applications, ranging from simple standalone operation to being part of complex power architecture. To preserve maximum flexibility, internal fusing is not included. This power module meets all safety agency requirements without presence of an input fuse. However, to achieve maximum safety and system protection, an input line fuse may be used. Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.

June 6, 2008 Austin SuperLynx IITM SMT Non-isolated Power Modules: 2.4 – 3.63Vdc input; 0.75Vdc to 2.0Vdc Output; 20A output current LINEAGE POWER 11 Design Considerations (continued) Output Filtering The Austin SuperLynx IITM SMT module is designed for low output ripple voltage and will meet the maximum output ripple specification with 1 µF ceramic and 10 µF tantalum 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. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified in the electrical specification table. 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, CSA C22.2 No. 60950-1-03, and VDE 0850:2001-12 (EN60950-1) Licensed. 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.
