LMR33620CQRNXTQ1 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and thermal vias to dissipate heat. A minimum of 2 oz copper thickness is recommended for optimal thermal performance.
  • Ensure the input voltage is within the recommended range of 2.7V to 5.5V, and the output voltage is within the recommended range of 0.8V to 5.5V. Also, ensure the device is operated within the recommended junction temperature range of -40°C to 125°C.
  • A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for the input capacitor. This value provides a good balance between noise filtering and stability.
  • Use a low-ESR output capacitor (e.g., X5R or X7R ceramic capacitor) with a value of 10uF to 22uF. Additionally, ensure the output capacitor is placed close to the device and connected to a solid ground plane to minimize noise and ripple.
  • The feedback network should be placed close to the device, and the feedback resistors should be placed as close as possible to the device pins. Use a single-point ground connection for the feedback network to minimize noise and oscillations.
