In this example, the maximum load for the boost converter is 50 mA, the minimum input voltage is 0.9 V, and the efficiency under this condition can be estimated at 80%, so the boost converter works in continuous operation mode by the calculation. The inductor peak current is calculated as 258 mA. To have some margin, a 4.7-µH inductor with at least 300 mA saturation current is recommended for this application. A 10-µH inductor can be used as well by increasing the output capacitance to higher than 22 µF to make the loop stable. Table 8-2 lists the recommended inductors for TPS61322xx device.
