Nexperia recommends a PCB layout with a thermal pad connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended, and the thermal pad should be connected to a ground plane or a heat sink.
The input capacitor selection depends on the input voltage, output voltage, and output current. A general rule of thumb is to choose a capacitor with a voltage rating at least 1.5 times the input voltage, and a capacitance value between 1uF to 10uF. Additionally, consider the capacitor's ESR (Equivalent Series Resistance) and ensure it is compatible with the device's switching frequency.
The NZX8V2B,133 can withstand a maximum voltage stress of 20V during startup or shutdown. However, it's recommended to limit the voltage stress to 15V or less to ensure reliable operation and minimize the risk of damage.
To ensure EMC, follow proper PCB layout and design guidelines, such as keeping the switching node (SW) away from sensitive nodes, using a common-mode choke, and adding shielding or filtering components as necessary. Additionally, consider using a spread-spectrum clock or frequency hopping to minimize electromagnetic interference (EMI).
The recommended operating temperature range for the NZX8V2B,133 is -40°C to 125°C. However, the device can operate up to 150°C for short periods during startup or shutdown, but prolonged operation above 125°C may affect its reliability and lifespan.
