LM5005MHX Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM5005MHX?
  The maximum input voltage that can be applied to the LM5005MHX is 60V, but it's recommended to keep it below 50V for reliable operation.
• How do I ensure the LM5005MHX operates within its thermal limits?
  To ensure the LM5005MHX operates within its thermal limits, make sure to provide adequate heat sinking, keep the ambient temperature below 85°C, and avoid high power dissipation.
• Can I use the LM5005MHX in a high-reliability or automotive application?
  Yes, the LM5005MHX is qualified for automotive and high-reliability applications, but you should consult the Texas Instruments website for specific documentation and qualification information.
• How do I layout the PCB to minimize electromagnetic interference (EMI) with the LM5005MHX?
  To minimize EMI, keep the LM5005MHX away from noise sources, use a solid ground plane, and ensure that the input and output capacitors are placed close to the device. Also, use a shielded inductor and keep the switching node (SW) as short as possible.
• What is the recommended input capacitor type and value for the LM5005MHX?
  The recommended input capacitor type is a low-ESR ceramic capacitor, and the value should be at least 10uF. However, the optimal value depends on the input voltage, output current, and PCB layout.
