NCP551SN31T1G Frequently Asked Questions (FAQs)

  • The recommended PCB layout for optimal thermal performance involves placing thermal vias under the IC, using a solid ground plane, and keeping the thermal traces as short and wide as possible. A 4-layer PCB with a dedicated thermal layer is also recommended.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF, with a low ESR (Equivalent Series Resistance) and a high ripple current rating. Additionally, the output voltage should be decoupled from the input voltage using a 1uF ceramic capacitor.
  • Although the datasheet specifies a maximum input voltage of 18V, it is recommended to limit the input voltage to 15V to ensure reliable operation and to prevent damage to the internal components.
  • The power dissipation of the device can be calculated using the formula: Pd = (Vin - Vout) x Iout x Efficiency. The efficiency of the device can be obtained from the datasheet or by using the onsemi power calculator tool.
  • The recommended input capacitor value is 1uF to 10uF, with a low ESR and a high ripple current rating. A ceramic or electrolytic capacitor with a voltage rating of at least 25V is recommended.
