2. Inductance is for the primary, measured from pins 12– 11 at 1 kHz, 0.1 Vrms.
3. DCR is for each winding of the primary and secondary.
4. Leakage inductance is for the primary windings, measured from pins 12– 11
with all secondary windings shorted.
5. Based on VIN max, FSW min and number of primary turns
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
