NCP3231MNTXG Frequently Asked Questions (FAQ)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the device can help to dissipate heat efficiently. It's also recommended to keep the thermal path short and use a thermal pad on the PCB.

  • Ensure that the input voltage (VIN) is within the recommended range (2.5V to 5.5V) and that the enable pin (EN) is properly biased to either VCC or GND. Also, make sure the output capacitor (COUT) is properly sized and placed close to the device.

  • A 1uF to 10uF ceramic capacitor (X5R or X7R dielectric) is recommended for the input capacitor (CIN). The capacitor should be placed close to the device and have a low ESR to minimize voltage ripple.

  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Iout is the output current, Cout is the output capacitance, and fsw is the switching frequency.

  • The maximum ambient temperature for the NCP3231MNTXG is 85°C. However, the device can operate up to 125°C junction temperature, but the ambient temperature should be derated accordingly to ensure reliable operation.
