Notes:

1. Inductance is measured at 250kHz, 0.3Vrms.

2. Peak primary current, Ipk, is drawn at minimum input voltage.

3. DCR for the primary and for the secondary are with the windings connected in parallel.

4. Leakage Inductance is for the primary winding with the secondary winding shorted.

5. Turns ratio are with the primary and the secondary windings connected in parallel.

6. Output of the secondary is with the windings connected in parallel. Bias winding output is 12V, 20mA.

7. Operating temperature range: -40°C to +125°C. The part temperature (ambient temperature + temperature rise)

should not exceed the upper limit of the operating temperature under worst case operating conditions. Circuit design,

component placement, PWB trace size and thickness, airflow and other cooling provisions all affect the part

temperature. Part temperature should be verified in the end application.
