RAC04-12SK/277 Frequently Asked Questions (FAQs)

  • The recommended PCB layout for optimal thermal performance involves placing the module on a multi-layer PCB with a large copper area for heat dissipation, ensuring good thermal conductivity and minimal thermal resistance.
  • To ensure reliable start-up and operation with a high-impedance input source, it is recommended to add a soft-start circuit or a high-value capacitor at the input to reduce the inrush current and prevent voltage drops.
  • The recommended input capacitors are low-ESR ceramic or film capacitors with a minimum capacitance of 10uF, while the recommended output capacitors are low-ESR ceramic or electrolytic capacitors with a minimum capacitance of 22uF.
  • To protect the module from overvoltage and undervoltage conditions, it is recommended to add overvoltage protection (OVP) and undervoltage protection (UVP) circuits, such as a voltage supervisor or a crowbar circuit, to prevent damage to the module.
  • The recommended thermal interface material for optimal heat transfer is a thermal pad or thermal tape with a thermal conductivity of at least 1 W/m-K, such as a silicone-based or graphite-based material.
