Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as keeping the high-current paths short and wide, using thermal vias, and separating the high-frequency and low-frequency components.
The input capacitor values depend on the input voltage, output voltage, and switching frequency. A general rule of thumb is to use a capacitor with a value between 10uF to 22uF, and a voltage rating of at least 1.5 times the input voltage. However, it's recommended to consult the datasheet and application notes for specific guidance.
The maximum junction temperature (Tj) for the CSD75211W1723 is 150°C. It's essential to ensure that the device operates within the recommended temperature range to prevent thermal shutdown and ensure reliability.
The CSD75211W1723 has built-in OCP and SCP features. To implement these features, you need to connect the OCP pin to a resistor and capacitor network, and the SCP pin to a resistor network. The datasheet provides detailed information on the recommended component values and implementation guidelines.
The recommended output capacitor value depends on the output voltage and current. A general rule of thumb is to use a capacitor with a value between 10uF to 47uF, and a type that can handle the output ripple current, such as an X5R or X7R ceramic capacitor.
