STMicroelectronics provides a recommended PCB layout in the application note AN4571, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
The input capacitor selection depends on the input voltage, ripple current, and ESR requirements. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the maximum input voltage, and an ESR of less than 1 ohm. STMicroelectronics recommends using a ceramic capacitor with an X7R or X5R dielectric.
The maximum allowed voltage drop across the internal FETs is not explicitly stated in the datasheet. However, according to STMicroelectronics' application notes, the voltage drop should be limited to 1.5V to ensure reliable operation and minimize power losses.
The SD2931-12MR is rated for operation up to 150°C, but the device's performance and reliability may degrade at high temperatures. It's essential to follow the recommended thermal design guidelines and consider derating the device's power handling capabilities at elevated temperatures.
To ensure EMC, follow the recommended PCB layout and component placement guidelines, use a shielded inductor, and add filtering components such as capacitors and resistors to minimize electromagnetic interference (EMI). Additionally, consider using a metal shield or enclosure to contain EMI radiation.
