LTM8049EY#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or heat sink to dissipate heat efficiently.
  • Ensure that the input voltage rises monotonically during start-up and falls monotonically during shutdown. A soft-start circuit can be used to control the inrush current and prevent voltage dips.
  • The maximum allowed capacitance is 100uF. Exceeding this value may cause instability or oscillations in the output voltage.
  • While it's possible to use a different inductor value or type, it's not recommended as it may affect the device's performance, efficiency, and stability. The recommended inductor value and type are optimized for the device's operating conditions.
  • Check the input voltage, output voltage, and feedback voltage to ensure they are within the specified ranges. Verify that the feedback resistors are correctly connected and that the output capacitor is properly sized and connected.
