LM97600CIUT/NOPB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pad connected to the ground plane to improve heat dissipation.
• How do I ensure the device operates within the recommended operating conditions?
  Monitor the input voltage, output voltage, and current to ensure they are within the specified ranges. Also, ensure the device is operated within the recommended temperature range of -40°C to 125°C.
• What is the recommended input capacitor type and value for optimal performance?
  A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended. The capacitor should be placed close to the VIN pin to minimize inductance.
• How do I minimize electromagnetic interference (EMI) in my design?
  Use a shielded inductor, keep the switching node (SW) away from sensitive nodes, and use a common-mode choke to reduce EMI. Also, ensure the PCB layout is optimized for minimal loop area and radiation.
• What is the recommended output capacitor type and value for optimal performance?
  A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended. The capacitor should be placed close to the VOUT pin to minimize inductance.
