LMR43620MSC3RPERQ1 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.
  • To ensure stability, it's essential to follow the recommended PCB layout, use a low-ESR output capacitor, and add a 10nF-100nF ceramic capacitor in parallel with the output capacitor. Additionally, ensure that the input capacitor is placed close to the VIN pin.
  • Although the datasheet specifies a maximum input voltage of 42V, it's recommended to limit the input voltage to 36V to ensure reliable operation and prevent damage to the device.
  • Choose an output capacitor with a low ESR (Equivalent Series Resistance) and a capacitance value between 10uF to 47uF. A ceramic or polymer capacitor with an X5R or X7R dielectric is recommended for optimal performance.
  • The LMR43620 is rated for operation up to 125°C. However, it's essential to consider the device's power dissipation and thermal management when operating in high-temperature environments. Ensure that the device is properly heatsinked and follow the recommended PCB layout for optimal thermal performance.
