See Figure 46: Hotspot temperature check points. Note 2 The control pin is referenced to Vin-. Note 3 The CXE15 is supplied as standard with active high logic. Control input pulled low: Unit disabled. Control input left open: Unit enabled. Figure 46: Hot Spot Location on all Models Note 4 Thermal reference set up: Unit mounted on an edge card test board 215mm x 115mm. Test board mounted vertically. 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. 23 www.artesyn.com CXE15 Single Series | 10.8 to 15W DC/DC High Efficiency DC/DC converters NORTH AMERICA e-mail: [email protected] ☎ 800 769 7274 ☎+ 508 628 5600 EUROPEAN LOCATIONS e-mail: [email protected] IRELAND ☎+ 353 24 93130 AUSTRIA ☎+ 43 1 80150 FAR EAST LOCATIONS e-mail: [email protected] HONG KONG ☎+ 852 2699 2868 LFDS_CXE15_20021001.PDF Long Form Data Sheet Artesyn Technologies® 2001 The information and specifications contained in this data sheet are believed to be correct at time of publication.
