LTM4660IY#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pads connected to the ground plane to improve heat dissipation.
  • Use a soft-start circuit to limit the inrush current during start-up. For shutdown, use a controlled ramp-down of the output voltage to prevent voltage spikes.
  • The LTM4660IY#PBF can drive up to 100nF of capacitive load. Exceeding this limit may cause oscillations or instability.
  • Use the datasheet's recommended compensation network values as a starting point. Then, adjust the values based on the specific application's requirements and PCB layout.
  • Use a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF. This helps to filter the input voltage and reduce noise.
