47124 Frequently Asked Questions (FAQs)

  • A 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern around the IC's thermal pad is recommended for optimal thermal performance.
  • To ensure reliable start-up and shutdown, add a soft-start circuit to limit the inrush current and prevent voltage drops. Also, use a capacitor with a low ESR value to filter the output voltage.
  • The maximum allowed voltage on the enable pin is 5.5V. Exceeding this voltage may damage the IC.
  • Yes, the 47124 is rated for operation up to 125°C. However, ensure proper thermal management and derate the output current accordingly to prevent overheating.
  • Check the PCB layout for noise coupling, ensure proper decoupling capacitors, and verify the output filter components are correctly selected. Also, check for voltage drops on the input and output lines.
