The maximum input voltage that the L6569AD013TR can handle is 30V, but it's recommended to keep it below 28V for reliable operation.
The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust based on the specific application requirements.
The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage for the power MOSFET. It's essential for proper operation of the converter and should be chosen according to the datasheet recommendations.
To ensure the L6569AD013TR operates within the recommended junction temperature range (up to 150°C), provide adequate heat sinking, use a thermally conductive PCB layout, and avoid excessive power dissipation.
To minimize EMI and noise, follow the recommended PCB layout guidelines in the datasheet, including keeping the power stage components close together, using a solid ground plane, and minimizing loop areas.
