NCP1027P100G Frequently Asked Questions (FAQs)

  • A recommended PCB layout for optimal thermal performance would be to have a solid ground plane on the bottom layer, and to use thermal vias to connect the exposed pad to the ground plane. This helps to dissipate heat efficiently.
  • To ensure reliable start-up, make sure the input voltage is within the recommended range, and the output capacitor is properly sized to handle the inrush current. Also, ensure that the input voltage rises monotonically to avoid false triggering of the under-voltage lockout (UVLO) circuit.
  • The maximum allowed capacitance on the output of the converter is 220uF. Exceeding this value may cause instability or oscillations in the converter.
  • 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, Cout is the output capacitance, and fsw is the switching frequency.
  • A recommended input capacitor value is 10uF to 22uF, with an X7R or X5R dielectric type. This helps to filter out input voltage noise and ensure stable operation.
