STMicroelectronics provides a recommended PCB layout in the application note AN4979, which includes guidelines for thermal pad connection, copper pouring, and via placement to ensure efficient heat dissipation.
The input capacitor selection depends on the input voltage, current, and frequency. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the maximum input voltage, and a capacitance value between 10uF to 100uF. Consult the application note AN4979 for more detailed guidance.
The maximum allowed voltage drop across the internal resistance (Rds(on)) is typically around 1.5V to 2V, depending on the specific application and operating conditions. Exceeding this limit may lead to reduced performance, increased power dissipation, or even device failure.
The T410-800B is rated for operation up to 150°C (TJ), but the device's performance and reliability may degrade at high temperatures. It's essential to consider the thermal management and derating factors when operating the device in high-temperature environments.
To ensure EMC, follow the guidelines in the application note AN4979, which includes recommendations for PCB layout, component selection, and shielding. Additionally, consider implementing EMI filters, and ensure that the device is properly decoupled and bypassed.
