LTM4644MPY#PBF Frequently Asked Questions (FAQ)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The device's thermal pad should be connected to the ground plane using multiple thermal vias.

  • Ensure that the input voltage rises monotonically and does not droop during start-up. A soft-start circuit can be used to control the input voltage rise time.

  • The maximum capacitive load is not explicitly stated in the datasheet, but as a general rule, it's recommended to limit the capacitive load to 10nF or less to ensure stability.

  • Yes, the LTM4644 is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. Ensure that the device is properly heatsinked and follow the recommended thermal design guidelines.

  • Check the PCB layout for noise coupling and ensure that the input and output capacitors are properly decoupled. Verify that the device is properly heatsinked and that the thermal pad is connected to the ground plane.
