STMicroelectronics provides a recommended PCB layout in the application note AN4899, which includes guidelines for thermal pad connection, copper pouring, and via placement to ensure optimal thermal performance.
The input capacitor selection depends on the input voltage, frequency, and ripple current. 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 1uF to 10uF. Consult the application note AN4899 for more detailed guidance.
The maximum allowed voltage drop across the VN750PT13TR is 1.5V. Exceeding this voltage drop may lead to reduced performance, increased power dissipation, or even device damage.
To ensure EMC, follow the guidelines in the application note AN4899, which includes recommendations for PCB layout, component selection, and shielding. Additionally, consider using a common-mode choke and a shielded cable for the input and output connections.
The recommended operating temperature range for the VN750PT13TR is -40°C to 150°C. However, the device can operate up to 175°C for short periods (less than 10 seconds) during startup or fault conditions.
