Inductor selection plays a critical role in the performance of the DRV2667 device. The range of recommended inductances is from 3.3 µH to 22 µH. In general, higher inductances within an inductor series of a given manufacturer have lower saturation current limits, and vice-versa. When a larger inductance is chosen, the device boost converter automatically runs at a lower switching frequency and incurs less switching losses; however, larger values of inductance may have higher equivalent series resistance (ESR), that increases the parasitic inductor losses. Because lower values of inductance generally have higher saturation currents, they are a better choice when attempting to maximize the output current of the boost converter. Ensure that the saturation current of the inductor selected is higher than the programmed current limit for the device.
