LMR43620RS3QRPERQ1 Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general best practices for switching regulator layout, such as keeping the input and output capacitors close to the IC, and using a solid ground plane to reduce noise and EMI.
  • To ensure the LMR43620RS3QRPERQ1 operates within its thermal limits, calculate the junction temperature (TJ) using the formula provided in the datasheet, and ensure it does not exceed the maximum rated TJ of 150°C. Also, consider using a thermal pad or heat sink to improve heat dissipation.
  • The recommended input capacitor type is a low-ESR ceramic capacitor, such as an X5R or X7R dielectric. The value should be at least 10uF, but a larger value may be required depending on the input voltage and output current requirements.
  • The output voltage of the LMR43620RS3QRPERQ1 can be adjusted by using a resistive divider network between the output and the FB pin. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
  • The maximum output current capability of the LMR43620RS3QRPERQ1 is 2A, but this may be limited by the thermal performance of the device and the PCB layout. It's recommended to derate the output current based on the ambient temperature and the device's thermal performance.
