MP2002DD-LF-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. The device should be placed near a thermal pad or a heat sink to dissipate heat efficiently.
• How do I ensure stability and prevent oscillations in the output voltage?
  Ensure that the output capacitor has a low ESR and is placed close to the device. Also, add a 10nF to 100nF ceramic capacitor in parallel with the output capacitor to filter out high-frequency noise.
• What is the maximum input voltage that can be applied to the device?
  The maximum input voltage is 24V, but it's recommended to keep it below 20V to ensure reliable operation and prevent damage to the device.
• How do I adjust the output voltage to a specific value?
  The output voltage can be adjusted by changing the ratio of the resistors R1 and R2 in the feedback network. Use the formula Vout = 0.8V x (1 + R2/R1) to calculate the required resistor values.
• What is the maximum output current that the device can deliver?
  The maximum output current is 2A, but it's recommended to keep it below 1.5A to ensure reliable operation and prevent overheating.
