4. 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) = 3.6E-14 * (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
5. The “NL” suffix indicates an RoHS-compliant part number. Non-NL suf-
fixed 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 con-
tact Pulse for availability.
