LDK120C18R Frequently Asked Questions (FAQs)

  • STMicroelectronics provides a recommended PCB layout in the application note AN2669, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
  • The input capacitor values depend on the input voltage, output voltage, and switching frequency. A general guideline is to use a capacitor with a value between 10uF to 22uF, with a voltage rating of at least 1.5 times the input voltage. Consult the datasheet and application notes for more specific guidance.
  • The LDK120C18R is rated for operation up to 85°C ambient temperature, but it's recommended to derate the output current and voltage to ensure reliable operation above 70°C. Consult the datasheet for thermal derating curves and guidelines.
  • To ensure EMC compliance, follow the guidelines in the application note AN2669, which includes recommendations for PCB layout, component selection, and shielding. Additionally, consider using a metal shield or a Faraday cage to enclose the converter, and ensure proper grounding and decoupling.
  • A low-ESR ceramic or film capacitor with a value between 10uF to 47uF is recommended for the output filter. The capacitor should be rated for at least 1.5 times the output voltage, and its ESR should be less than 100 mΩ to ensure stable operation.
