See Figure 10: Thermal reference points. Case Temperature should not exceed 115ºC Note 2 The Remote ON/OFF pin is referenced to ground. Note 3 The SMT15E-12 features an ‘Active High’ Remote ON/OFF operation. If not using the Remote ON/OFF pin, leave the pin open (the converter will be on). The Remote ON/OFF pin is referenced to ground. The following conditions apply for the SMT15E: Configuration Remote pin open circuit Remote pin pulled low [Von/off <.8V] Remote pin pulled high [Von/off >1.6V] Converter Operation Unit is ON Unit is OFF Unit is ON Direction of Airflow A an ‘Active Low’ Remote ON/OFF version is also possible with this converter. Please consult the factory for details. Figure 10: Thermal Reference Points Note 4 Thermal reference set up: Unit mounted on an edge card test board 203mm x 190mm. Test board mounted vertically. For test details and recommended set-up see Application Note 142. Note 5 Max 60ºC for full load in still air. See Application Note 142 for a detailed thermal Derating.
