2 / 8 page 2 Lineage Power LAW005-Series Power Modules; dc-dc Converters: Data Sheet 36 Vdc to 75 Vdc Input; 5 W April 2008 Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso- lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability. * At IO = IO, max, derate linearly to 0 W at 100 °C. Unit guaranteed to start at –40 °C. All parameters will be within specification at TA = –25 °C. Electrical Specifications Unless otherwise indicated, specifications apply over all operating input voltage and resistive load from –25 °C to +71 °C. Fusing Considerations CAUTION: This power module is not internally fused. An input line fuse must always be used. This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fus- ing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow fuse with a maximum rating of 5 A (see Safety Considerations section). 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 for further information.
