... The EN pin of the AOZ1024D is active HIGH. Connect the EN pin enable function is not used. Pulling ground will disable the AOZ1024D. Do not leave it open. The voltage on EN pin must be above 2V to enable the AOZ1024D. When voltage on the EN pin falls below 0.6V, the AOZ1024D is disabled application circuit ...

... Figure 1. Component selection is explained below. Input capacitor The input capacitor must be connected to the V PGND pin of AOZ1024D to maintain steady input voltage and filter out the pulsing input current. The voltage rating of input capacitor must be greater than maximum input voltage plus ripple voltage. ...

... In PCB layout, minimizing the two loops area reduces the noise of this circuit and improves efficiency. A ground plane is strongly recommended to connect input capaci- tor, output capacitor, and PGND pin of the AOZ1024D. In the AOZ1024D buck regulator circuit, the major power dissipating components are the AOZ1024D and the output inductor. The total power dissipation of converter circuit can be measured by input power – ...
