NCP1012AP133G 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 minimum of 2oz copper thickness is recommended for the thermal pad.
  • To ensure reliable startup of the device, it is recommended to use a soft-start circuit to limit the inrush current during startup, and to ensure that the input voltage rises slowly (typically 10-20ms) to prevent voltage spikes.
  • The maximum allowed voltage on the EN pin is 6V, exceeding which may cause damage to the device. It is recommended to use a voltage divider or a zener diode to limit the voltage on the EN pin.
  • 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, and the recommended value is 10-22uF. The input capacitor should be placed as close as possible to the device's VIN pin.
