NCP161ASN330T1G Related Parts

NCP161ASN330T1G Frequently Asked Questions (FAQ)

  • A good PCB layout for the NCP161ASN330T1G should include a solid ground plane, wide power traces, and a thermal relief pattern under the device to facilitate heat dissipation. A minimum of 2oz copper thickness is recommended.

  • To ensure reliable start-up, ensure that the input voltage is within the specified range, the output voltage is set correctly, and the soft-start capacitor is properly sized. Also, ensure that the input voltage rises monotonically during start-up.

  • The maximum allowed output capacitance for stability is dependent on the specific application and output voltage. As a general guideline, the output capacitance should be limited to 10uF or less to ensure stability. However, it's recommended to consult with onsemi's application engineers for specific guidance.

  • The NCP161ASN330T1G has built-in OCP and SCP features. To handle these events, ensure that the OCP threshold is set correctly, and the SCP response time is adjusted according to the application requirements. Additionally, consider adding external protection components, such as fuses or PTCs, for added protection.

  • A recommended input filter design for EMI compliance includes a pi-filter configuration with a common-mode choke, X-capacitors, and Y-capacitors. The specific component values and layout should be optimized for the target application and regulatory requirements.
