1. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc.
2. Ipk is peak primary current drawn at minimum input voltage.
3. DCR for the primary is measured with the windings connected in parallel.
4. Leakage inductance is for the primary winding, measured at 100 kHz,
0.1 Vrms, 0 A with secondary pins shorted.
6. Output is for the secondary. Output of the auxiliary coil is 19 V, 20 mA.
5. Electrical specifications at 25°C.
