When using remote sense and trim the output voltage of the module is usually increased which increases the power output of the module with the same output current Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power THERMAL CONSIDERATIONS Thermal management is an important part of the system design To ensure proper reliable operation sufficient cooling of the power module is needed over the entire temperature range of the module Convection cooling is usually the dominant mode of heat transfer Hence the choice of equipment to characterize the thermal performance of the power module is a wind tunnel Thermal Testing Setup Delta s DC DC power modules are characterized in heated vertical wind tunnels that simulate the thermal environments encountered in most electronics equipment This type of equipment commonly uses vertically mounted circuit cards in cabinet racks in which the power modules are mounted The following figure shows wind tunnel characterization setup The power module is mounted on a test PWB and is vertically positioned within the wind tunnel The space between the neighboring PWB and the top of the power module is constantly kept at 6 35mm 0 25 FACING PWB PWB MODULE AIR VELOCITY AND AMBIENT TEMPERATURE MEASURED BELOW THE MODULE 50 8 2 07 ARROW NEP Note Wind Tunnel Test Setup Fi
