NCS3402DR2G Frequently Asked Questions (FAQs)

  • A good PCB layout for the NCS3402DR2G involves keeping the input and output traces short and away from each other, using a solid ground plane, and placing decoupling capacitors close to the device. Additionally, it's recommended to use a shielded inductor and to keep the switching node (SW) away from sensitive analog nodes.
  • The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value recommended in the datasheet (e.g., 1.5 μH for the NCS3402DR2G). Then, adjust the value based on the specific application requirements, such as output voltage ripple and efficiency.
  • The maximum ambient temperature for the NCS3402DR2G is 125°C. However, the device can operate at higher temperatures with derating. It's essential to consider the thermal design and heat dissipation in the system to ensure reliable operation.
  • To ensure stability, follow the recommended component values and PCB layout guidelines. Additionally, ensure that the output capacitor is sufficient to filter the output voltage, and the feedback network is properly designed. It's also recommended to add a small capacitor (e.g., 10 nF) between the COMP pin and GND to improve stability.
  • A ceramic capacitor with a value of 10 μF to 22 μF is recommended for the input capacitor. The capacitor should have a voltage rating of at least 1.5 times the maximum input voltage. X5R or X7R dielectric capacitors are suitable for this application.
