LMR36520ADDAR Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the device can help to dissipate heat efficiently. It's also recommended to keep the thermal pads connected to a large copper area to improve heat dissipation.
  • To ensure stability, it's essential to follow the recommended layout and component placement guidelines, use a low-ESR output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the VIN and GND pins to filter out high-frequency noise.
  • Although the datasheet specifies a maximum input voltage of 36V, it's recommended to limit the input voltage to 30V to ensure reliable operation and prevent damage to the device.
  • The output voltage ripple and noise can be estimated using the equations provided in the datasheet. Additionally, the output capacitor's ESR and ESL, as well as the inductor's DCR, can affect the output voltage ripple and noise.
  • A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value between 4.7μF and 10μF is recommended for the input capacitor. This helps to filter out high-frequency noise and ensure stable operation.
