FAN2558SX Frequently Asked Questions (FAQ)

  • The FAN2558SX can operate from -40°C to 150°C, making it suitable for high-reliability applications.

  • To ensure proper biasing, connect the VCC pin to a stable 5V power supply, and the GND pin to a solid ground plane. Also, decouple the VCC pin with a 0.1uF capacitor to reduce noise.

  • To minimize electromagnetic interference (EMI) and ensure signal integrity, use a multi-layer PCB with a solid ground plane, and keep the input and output traces short and separate. Avoid routing signals under the device.

  • To minimize switching noise, use a ferrite bead or a common-mode choke on the output, and add a 10nF capacitor in parallel with the output resistor. Also, ensure the PCB layout is optimized for low inductance and capacitance.

  • During startup, the FAN2558SX has a soft-start feature that ramps up the output voltage to prevent inrush currents. During shutdown, the device enters a low-power state, and the output voltage decays rapidly to minimize energy loss.
