STMicroelectronics provides a recommended PCB layout in the application note AN4101, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
STMicroelectronics provides a configuration tool, the LD29300 Configurator, which allows users to select the desired configuration options, such as output voltage, switching frequency, and protection features, and generates a configuration file that can be used to program the device.
The recommended input and output capacitors are listed in the datasheet, but it's also important to consider the capacitor's ESR, voltage rating, and temperature rating to ensure reliable operation. A good starting point is to use X7R or X5R ceramic capacitors with a voltage rating of at least 1.5 times the input voltage and a temperature rating of 125°C or higher.
STMicroelectronics provides a troubleshooting guide in the application note AN4102, which includes a step-by-step approach to identifying and resolving common issues, such as oscillations, instability, and overvoltage protection triggers.
The thermal derating guidelines are provided in the datasheet, but it's also important to consider the device's power dissipation, ambient temperature, and airflow when designing the system. A good rule of thumb is to derate the device's power rating by 1-2% per degree Celsius above the recommended operating temperature range.
