See Figure 30: Hotspot temperature check points. Note 2 The control pin is referenced to Vin-. Note 3 The SXE15 features `Active High' Remote ON/OFF as standard. An `Active Low' Remote ON/OFF version is also available. To order the `Active Low' version of the SXE15-48D05-3V3J please add the suffix `-R' towards the end of the part number, i.e. SXE15-48D05-3V3-RJ. As our part numbers cannot exceed 18 characters when ordering the `Active Low' version of the SXE15-48D3V3-2V5J please add the suffix `R' towards the end of the part number, i.e. SXE15-48D3V3-2V5RJ. 1 Figure 46: Hot Spot Locations on all Models Note 4 Thermal reference set up: Unit mounted centrally on a 200mm x 240 mm testboard. Testboard is mounted vertically in a fully enclosed 300mm x 300mm x 300mm testbox. Ambient temperature measured at the bottom of the textbox. Altitude sea level. For test details and recommended set-up see Application Note 116. CAUTION: Hazardous internal voltages and high temperatures. Ensure that unit is accessible only to trained personnel. The user must provide the recommended fusing in order to comply with safety approvals. 19 www.artesyn.com File Name: lf_sxe15d.pdf Rev: 29 Mar 2006 SXE15 Dual Series | 15W DC/DC High Efficiency DC/DC Converters NORTH AMERICA e-mail: sales.us@artesyn.com % 800 769 7274 %+ 508 628 5600 EUROPEAN LOCATIONS e-mail: sales.europe@artesyn.com IRELAND %+ 353 24 93130 AUSTRIA %+ 43 1 80150 FAR EAST LOCATIONS e-mail: sales.asia@artesyn.com HONG KONG %+ 852 2699 2868 Longform Datasheet Artesyn Technologies(R) The information and specifications contained in this datasheet are believed to be correct at time of publication.
