Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as keeping the input and output traces separate, using a solid ground plane, and minimizing loop areas to reduce EMI.
The input capacitor selection depends on the input voltage, current, and frequency. A general rule of thumb is to choose a capacitor with a voltage rating at least 1.5 times the maximum input voltage, and a capacitance value between 1uF to 10uF. X5R or X7R ceramic capacitors are suitable for most applications.
The TPS65563ARGTR has a maximum output current rating of 1.5A. However, it's essential to consider the thermal limitations and power dissipation when operating at high currents. Ensure the device is properly heatsinked and the ambient temperature is within the recommended range.
The TPS65563ARGTR has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold is set by the voltage divider ratio. Consult the datasheet for specific implementation details and equations.
The EN (enable) pin is used to turn the device on or off. When the EN pin is pulled low, the device enters a low-power shutdown mode. This pin can be used to implement power sequencing or to reduce power consumption in standby modes.
