LMR33620CQRNXRQ1 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and a thermal relief pattern under the device to improve thermal performance. A minimum of 2 oz copper thickness is recommended.
  • 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 operates within the recommended junction temperature range of -40°C to 125°C.
  • A ceramic capacitor with a value of 1uF to 10uF is recommended for the input capacitor. The capacitor should be placed as close to the device as possible to minimize noise and ensure optimal performance.
  • Use a low-ESR output capacitor with a value of 1uF to 10uF, and place it as close to the device as possible. Additionally, use a noise-reducing capacitor, such as a 10nF ceramic capacitor, between the output and ground to filter out high-frequency noise.
  • For high-power applications, a heat sink with a thermal resistance of less than 10°C/W is recommended. Ensure good thermal contact between the device and the heat sink, and use a thermal interface material to minimize thermal resistance.
