RLS4148 Frequently Asked Questions (FAQ)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces short and away from each other to minimize noise coupling.

  • Ensure that the output capacitor is properly sized and placed close to the output pin. Also, use a low-ESR capacitor and keep the feedback network impedance low to prevent oscillations.

  • The maximum input voltage is 42V, but it's recommended to keep it below 36V to ensure reliable operation and prevent damage to the device.

  • Yes, the RLS4148 is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Ensure proper thermal design and heat sinking to prevent overheating.

  • Use an external current sense resistor and a fuse or a current limiter to protect the device from overcurrent conditions. Also, ensure that the output is short-circuit protected to prevent damage.
