Notes
• 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 V
IN
and V
OUT
to 25 V

In this configuration, current flowing opposite directions through
coils cancels and the 0.1 μH inductance is very stable with
varying current. Observe the heat rating current to avoid
excessive temperature rise in this configuration
