LMR62421XSDE/NOPB 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. It's also recommended to keep the thermal path short and use a thermal pad on the bottom of the device.
  • To ensure stability, it's essential to follow the recommended component values and PCB layout guidelines. Additionally, a minimum ESR (Equivalent Series Resistance) of 10mΩ for the output capacitor is recommended to prevent oscillations.
  • The maximum SOA for the LMR62421XSDE/NOPB is defined by the maximum junction temperature (TJ) of 150°C, and the maximum input voltage (VIN) of 42V. Operating the device within these limits ensures reliable operation and prevents damage.
  • The output voltage ripple and noise can be calculated using the equations provided in the datasheet. The output voltage ripple is primarily dependent on the output capacitor value, ESR, and the switching frequency. Noise can be minimized by using a low-ESR output capacitor and a well-designed PCB layout.
  • The recommended input capacitor is a 10uF to 22uF ceramic or electrolytic capacitor with a low ESR (<10mΩ). The recommended output capacitor is a 10uF to 47uF ceramic or electrolytic capacitor with a low ESR (<10mΩ).
