• All test data is referenced to 25 °C ambient
• Operating temperature range -55 °C to +155 °C
• The part temperature (ambient + temp. rise) should not exceed 155 °C 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
• Rated operating voltage (across inductor) = 50 V
• SEPIC operation can generate up to 2x the input or output voltage across the inductor. Please limit VIN and VOUT to 25 V max. for SEPIC operation
(1) DC current (A) that will cause an approximate T of 40 °C (2) DC current (A) that will cause L0 to drop approximately 20 % (3) In this configuration, current flowing opposite directions through
coils cancels and the 1.5 μH inductance is very stable with varying current.
