NOTES:
1. Typical inductance occurs at the IDC and ETOP values shown.
4. Inductance increases with increase in BOP or ETOP.
2. The control value of inductance is measured at BOP equal to or
less than 10 gauss (10 mV @ 20 kHz) without DC current.
5. SIMPLE SWITCHER™ is a trademark of National
Semiconductor Corporation.
3. Inductance decreases with higher values of DC current and
increases with lower values of DC current.
