See Figure 30: Hotspot temperature check points. Note 2 The control pin is referenced to Vin-. Note 3 The SXN15 is supplied as standard with active high logic. Control input pulled low: unit disabled. Control input floating: unit enabled. The unit can be supplied with active low logic. 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 Figure 30: Hot Spot Locations on all Models SXN15 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 LFDS_SXN15D_20011115.PDF Long Form Data Sheet Artesyn Technologies(R) 2001 The information and specifications contained in this data sheet are believed to be correct at time of publication.
