STMicroelectronics provides a recommended PCB layout in the application note AN4979, which includes guidelines for thermal management, decoupling, and layout considerations to ensure optimal performance and minimize electromagnetic interference (EMI).
The input capacitor values depend on the input voltage, output voltage, and switching frequency. A general guideline is to use a capacitor with a value between 10uF to 22uF, with a voltage rating of at least 1.5 times the input voltage. Refer to the application note AN4979 for more detailed guidance.
The enable pin (EN) can withstand a maximum voltage of 6V, which is higher than the recommended operating voltage of 5V. However, it's recommended to keep the EN pin voltage within the recommended operating range to ensure reliable operation.
The VNV35NV04TR-E is rated for operation up to 150°C, but the device's performance and reliability may degrade at high temperatures. It's essential to consider the thermal management and ensure the device operates within the recommended temperature range to maintain optimal performance and reliability.
STMicroelectronics provides a troubleshooting guide in the application note AN4979, which covers common issues such as output voltage regulation, efficiency, and thermal management. Additionally, the datasheet provides a list of possible faults and their corresponding troubleshooting steps.
