STMicroelectronics provides a recommended PCB layout in their application note AN2344, which includes guidelines for thermal pad connection, copper pour, and via placement to ensure optimal thermal performance.
The input capacitor selection depends on the input voltage, output voltage, and output current. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the input voltage, and a capacitance value between 1uF to 10uF. Refer to the application note AN2344 for more detailed guidance.
The maximum allowed voltage on the bootstrap pin (VBST) is typically limited to 6V to 7V, depending on the specific application and operating conditions. Exceeding this voltage may damage the internal bootstrap diode. Consult the datasheet and application notes for specific guidance.
To ensure proper biasing for high-frequency operation, follow the recommended biasing scheme in the datasheet and application notes. This typically involves connecting the VCC pin to a stable voltage source, and ensuring the input voltage is within the recommended range. Additionally, decoupling capacitors and proper PCB layout are crucial for high-frequency operation.
The recommended operating temperature range for the 2STD2360T4 is -40°C to 150°C. However, the device can operate up to 175°C for short periods of time. Consult the datasheet and application notes for specific guidance on thermal management and derating.
