Notes:

1. Inductance is measured at 100kHz, 0.1Vrms.

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

3. DCR for the secondary is with the windings connected in parallel.

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

for the drive winding is with the secondary windings shorted.

5. Turns ratio is with the secondary windings connected in parallel.

6. Output of the secondary is with the windings connected in parallel. Bias winding output is 10V, 20mA.

7.Operating temperature range: -40°

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.
