The temperature of the component (ambient plus temperature rise) must be 3. In high volt-sec applications, it is important to calculate the core loss of the within the stated operating temperature range. transformer. Approximate transformer core loss can be calculated as: 1.63 2.63 2. For flyback topology applications, it is necessary to ensure that the trans- CoreLoss (W) = 3.9E-13 * (Freq kHz) * (DB Gauss) former will not saturate in the application. The peak flux density (Bpk) should where DB can be calculated as: remain below 2700Gauss. To calculate the peak flux density use the follow- For Flyback Topology: DB = K1 Factor * D(A) ing formula: For Forward Topology: DB = K1 Factor * Volt-sec Bpk (Gauss) = K1 Factor * Ipk(A) 4. The NL suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are not necessarily RoHS compliant, but are electrically and mechani- cally equivalent to NL versions. If a part number does not have the NL suffix, but an RoHS compliant version is required, please contact Pulse for availability.
