NOTES:
1.DC current (I
dc
) that will cause an approximate
△T
of 40℃
2.DC current (I
sat
) that will cause Lo to drop approximately 20%
3.All test data is referenced to 25℃ ambient
4.Operating Temperature Range -55℃ to +150℃
5.The part temperature (ambient + temp rise) should not exceed 150℃
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.
