NXP provides a recommended PCB layout in the application note AN11160, which includes guidelines for thermal pad connection, thermal vias, and copper pour to ensure optimal thermal performance.
The input capacitor selection depends on the input voltage, output voltage, and output current. NXP recommends using a low-ESR capacitor with a value between 4.7uF to 10uF, and a voltage rating of at least 1.5 times the input voltage. Refer to the application note AN11160 for more details.
The maximum allowed voltage on the enable pin is 6V. Exceeding this voltage may damage the device. It's recommended to use a voltage divider or a level shifter to ensure the enable pin voltage is within the specified range.
To ensure a stable operating condition during startup, NXP recommends using a soft-start circuit or a ramp-up circuit to slowly increase the input voltage. This helps to prevent inrush currents and ensures a stable output voltage.
The recommended operating temperature range for the PHD101NQ03LT,118 is -40°C to 125°C. Operating the device outside this range may affect its performance, reliability, and lifespan.
