LME49870MA/NOPB Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for optimal performance. TI recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, it's recommended to use a common mode choke and a shielded inductor to reduce EMI.
  • To ensure stability, make sure to follow the recommended component values and PCB layout. Also, ensure that the output capacitor is properly sized and that the feedback network is properly compensated. Additionally, consider using a soft-start circuit to reduce inrush current during startup.
  • The maximum input voltage that can be applied to the LME49870MA/NOPB is 42V. Exceeding this voltage may cause damage to the device.
  • The LME49870MA/NOPB has built-in overcurrent protection, but it's still important to add external protection such as a fuse or a current sense resistor. Additionally, ensure good thermal design and heat sinking to prevent overheating.
  • The LME49870MA/NOPB is rated for operation up to 125°C. However, it's recommended to derate the device's performance at high temperatures. Consult the datasheet for more information on thermal derating.
