NCP703SN33T1G 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.
  • To ensure stable output voltage regulation, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1ohm or less. Additionally, the output capacitor should be placed as close to the output pin as possible to minimize parasitic inductance.
  • 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 prevent damage to the device.
  • The NCP703SN33T1G has a built-in overcurrent protection (OCP) feature that limits the output current to 3.3A. However, it is still recommended to add external overcurrent protection, such as a fuse or a current sense resistor, to prevent damage to the device and the PCB.
  • A minimum input capacitance of 1uF with an X7R or X5R dielectric is recommended. The input capacitor should be placed as close to the input pin as possible to minimize parasitic inductance.
