NCP303151MNTWG Frequently Asked Questions (FAQs)

  • A thermal pad on the bottom of the package should be connected to a large copper area on the PCB to dissipate heat. A minimum of 2oz copper thickness is recommended. Additionally, vias should be placed under the thermal pad to connect to an internal copper plane or a heat sink.
  • The device requires a stable input voltage (VIN) and a bypass capacitor (CBYP) to ensure proper biasing. A 10uF ceramic capacitor is recommended for CBYP. Additionally, the input voltage should be filtered using an LC filter or a ferrite bead to reduce noise.
  • The maximum output current capability of the NCP303151MNTWG is 1.5A. However, the output current should be derated based on the ambient temperature and the PCB's thermal design.
  • The device has built-in overvoltage protection (OVP) and undervoltage lockout (UVLO) features. However, additional protection can be achieved by using a voltage supervisor or a reset IC to monitor the input voltage and reset the system if it falls outside the recommended operating range.
  • A 10uF to 22uF ceramic capacitor with an X5R or X7R dielectric is recommended for the input capacitor (CIN). The capacitor should be placed as close to the VIN pin as possible to minimize noise and ripple.
