MP8758HGL-Z - Monolithic Power Systems (MPS)

MP8758HGL-Z Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the switching node (SW pin) away from sensitive analog nodes, and use a thermal relief pattern under the IC to improve heat dissipation.
• How do I optimize the output voltage accuracy and stability?
  Use a high-quality output capacitor with low ESR, and ensure the feedback network is properly compensated. Also, minimize the distance between the output capacitor and the IC, and use a low-impedance connection to the output capacitor.
• What is the maximum input voltage that can be applied to the VIN pin?
  The maximum input voltage is 26V, but it's recommended to keep it below 24V for optimal reliability and performance. Exceeding 26V may cause damage to the IC.
• How do I ensure the device meets the required electromagnetic interference (EMI) standards?
  Use a shielded inductor, keep the switching node (SW pin) away from sensitive analog nodes, and ensure the PCB layout is optimized for EMI reduction. Additionally, consider adding EMI filters or shielding to the device.
• What is the recommended input capacitor type and value for optimal performance?
  A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value between 4.7uF to 10uF is recommended. The capacitor should be placed close to the VIN pin and have a low impedance connection to the IC.
