10.2.1.2.1 Surface Mount Inductor

Working inductance decreases as inductor current increases. if the drop in working inductance is severe enough, it may cause the boost converter to become unstable, or cause the TPA2080D1 to reach its current limit at a lower output power than expected. Inductor vendors specify currents at while inductor values decrease by a specific percentage. This can vary from 10% to 35%. Inductance is also affected by DC current and temperature.
