ISL8117FRZ-T Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pad connected to the ground plane to improve heat dissipation.
  • Monitor the input voltage, output voltage, and output current to ensure they are within the specified ranges. Also, ensure the device is operated within the recommended temperature range.
  • A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF is recommended for the input capacitor.
  • Use a shielded inductor, keep the switching node (SW) away from sensitive nodes, and use a common-mode choke to reduce EMI. Also, ensure good PCB layout practices, such as keeping the power stage away from sensitive analog circuits.
  • A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF is recommended for the output capacitor. The output capacitor should be placed close to the output pin to minimize parasitic inductance.
