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) 6. 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) = 7E-12 * (Freq_kHz)1.88 * (∆B_Gauss)2.52 where ∆B can be calculated as: For Flyback Topology: ∆B = K1_Factor * ∆(A) 8Vin : 12V 350KHz Vout 1 : 20V/0.12A 17 5 Vout 2 : -5.5V/0.12A PM9595.XXNL Mechanical Scematic 5.08+/-0.30

The voltage required across the gate-source terminals of a SiC-MOSFET are typically found in the range of 14 to 20 V for full turn-on and 0 to -5 V for robust turn-off. The transformer is compatible with flyback controllers such as ADI 8301/2 for a system connection as shown below In addition to the providing galvanic isolation between the high-voltage and low-voltage sides, the purpose of the transformer is to satisfy the requirements of the relevant safety standards. PM9595NL is designed to comply with the IEC61558-1 & -2/16 for basic and reinforced insulation. With 8.3mm creepage distance and based on material group III, OVCII and 4000m altitude, this corresponds to a maximum working voltage of 800V for basic insulation and 390V0 for reinforced insulation.
