FLYBACK TRANSFORMER
High Frequency Wire Wound Transformers
EFD15 Platforms - SMT
Notes
The temperature of the component (ambient plus temperature rise) must be within the stated
operating temperature range.
2. The above transformers and inductors have been tested and approved by Pulse’s power IC
partners and are sited in the appropriate datasheet or evaluation board documentation at these
companies. To determine which IC and IC partners are matched with the above Pulse part numbers
please consult the IC Cross Reference on the Pulse website.
3. 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)
1.
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) = 4.6E-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. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (i.e.
PA0476NL becomes PA0476NLT). Pulse complies with industry standard tape and reel specification
EIA481. The tape and reel for this product has a width (W=44mm), pitch (Po=32mm) and depth
(Ko=11.78mm).
6. The “NL” suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are not neces-
sarily 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.
