LTM4644EY#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 during start-up and falls monotonically during shutdown. A soft-start circuit can be used to control the input voltage ramp rate.

  • The maximum capacitive load is dependent on the output voltage and frequency. As a general guideline, the device can drive up to 10nF of capacitance. However, it's recommended to consult with Analog Devices' application engineers for specific guidance.

  • Use a shielded inductor, keep the switching node (SW) away from sensitive nodes, and use a common-mode choke to reduce EMI. Additionally, ensure that the PCB layout is optimized for minimal loop area and radiation.

  • A pi-filter (L-C-R) or a differential filter (L-C-L) can be used to reduce input ripple. The filter components should be chosen based on the input voltage, frequency, and desired attenuation.
