FAN48623UC50X Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the IC is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.
  • Ensure that the input voltage rises and falls monotonically, and that the input capacitor is properly sized to filter out noise and ripple. Also, add a soft-start circuit to limit inrush current during start-up.
  • The maximum allowed voltage on the EN pin is 6V. To protect it from overvoltage, use a voltage divider or a zener diode to clamp the voltage to a safe level.
  • Use the recommended compensation network values in the datasheet as a starting point, and then adjust them based on the specific application requirements and PCB layout. You can also use simulation tools to optimize the compensation network.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended. The capacitor should be placed close to the VIN pin to minimize noise and ripple.
