The above transformers have been tested and approved by Pulse's IC partners and are cited in the appropriate datasheet or evaluation board documentation at these companies. To determine which IC and IC companies are matched with the above transformers, please refer to the IC cross reference on the Pulse web page. Other winding configurations are available. Please contact Pulse Power Applications Engineering for more information. 2. To determine if the transformer is suitable for your application, it is necessary to ensure that the temperature rise of the component (ambieint plus temperature rise) does not exceed its operating temperature. To determine the approximate temperature rise of the transformer, refer to the graphs below.
