LMR33620BDDAR 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. TI also recommends using a thermal pad on the bottom of the device.
  • To ensure stability, use a minimum output capacitance of 10uF, and ensure that the output voltage is within the recommended range. Also, use a low-ESR capacitor and keep the feedback loop as short as possible.
  • The maximum input voltage rating is 42V, but it's recommended to operate within 36V to ensure reliable operation and prevent damage to the device.
  • The output voltage can be calculated using the formula: Vout = (R1/R2) * (1.21V), where R1 and R2 are the resistors in the feedback network.
  • The maximum output current rating is 2A, but it's recommended to operate within 1.5A to ensure reliable operation and prevent overheating.
