... The inductor parameters directly related to the device’s perfor- mances are saturation current and dc resistance. The FAN2001/ FAN2002 operates with a typical inductor value of 3.3µH. The lower the dc resistance, the higher the efficiency. For saturation current, the inductor should be rated higher than the maximum load current plus half of the inductor ripple current ...

... Figure 6. Recommended PCB Layout (FAN2002) FAN2001/FAN2002 Rev. 1.0.2 Therefore, use wide traces for high current paths and place the input capacitor, the inductor, and the output capacitor as close as possible to the integrated circuit terminals. In order to mini- mize voltage stress to the device resulting from ever present switching spikes, use an input bypass capacitor with low ESR ...
