DM FLYBACK TRANSFORMER
3. In high volt-µsec applications, it is important to calculate the core loss of the
transformer. Approximate transformer core loss can be calculated as:
CoreLoss (W) = 3.9E-13 * (Freq_kHz)1.63 * (DB_Gauss)2.63
where DB can be calculated as:
For Flyback Topology: DB = K1_Factor * D(A)
For Forward Topology: DB = K1_Factor * Volt-µsec
4. The “NL” suffix indicates an RoHS-compliant part number. Non-NL suffixed
parts are not necessarily RoHS compliant, but are electrically and mechanically 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.

1. The temperature of the component (ambient plus temperature rise) must be
within the stated operating temperature range.
2. For flyback topology applications, it is necessary to ensure that the transformer will not saturate in the application. The peak flux density (Bpk) should
remain below 2700Gauss. To calculate the peak flux density use the following formula:
Bpk (Gauss) = K1_Factor * Ipk(A) PRI
