NCP1076BBP065G Frequently Asked Questions (FAQs)

  • The recommended PCB layout for optimal thermal performance involves placing the device on a thermal pad connected to a large copper area on the PCB, and ensuring good airflow around the device. A 4-layer PCB with a dedicated thermal layer is also recommended.
  • To ensure reliable startup, ensure that the input voltage rises monotonically and does not droop during startup. Also, add a soft-start capacitor (Css) to limit the inrush current and prevent voltage overshoots.
  • 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.
  • The recommended input capacitor type is a low-ESR ceramic capacitor, such as an X5R or X7R dielectric. The recommended value is 10uF to 22uF, depending on the input voltage and current requirements.
