LTM4649IY Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias connecting the exposed pad to the ground plane is recommended. This layout helps to dissipate heat efficiently and reduces thermal resistance.
  • Use the output filter design tool provided by Analog Devices or follow the guidelines in the datasheet to select the optimal output filter components. A higher value of output capacitance and a lower value of ESR can help reduce ripple and noise.
  • The maximum allowed input voltage transient for the LTM4649IY is 18V. Exceeding this voltage may damage the device.
  • 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 rise time of the input voltage.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. This helps to reduce input voltage ripple and noise.
