SSL2103T/1,518 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. Ensure a minimum of 1mm clearance around the device for airflow and heat dissipation.
• How do I ensure reliable start-up and shutdown of the SSL2103T?
  Use a soft-start circuit to limit inrush current during start-up. For shutdown, ensure a controlled ramp-down of the output voltage to prevent voltage spikes.
• What are the critical components to consider for EMI filtering?
  Use a common-mode choke, X-capacitors, and Y-capacitors to filter EMI. Ensure the filter components are placed close to the SSL2103T to minimize radiation.
• How do I optimize the output voltage ripple and noise?
  Use a low-ESR output capacitor (e.g., ceramic or film capacitor) and consider adding a pi-filter or LC-filter to reduce ripple and noise.
• What is the recommended input capacitor type and value?
  Use a low-ESR, high-frequency capacitor (e.g., ceramic or film capacitor) with a value between 1uF to 10uF, depending on the input voltage and frequency.
