SW-328 Frequently Asked Questions (FAQ)

  • Stancor recommends a 4-layer PCB with a solid ground plane, and keeping the input and output traces as short as possible to minimize noise and EMI. Additionally, a 10nF capacitor between the input and output pins can help reduce ringing.

  • The SW-328 is rated for operation from -40°C to +85°C. Ensure proper heat sinking, avoid overheating, and keep the device away from high-temperature sources. Also, consider derating the output power at high temperatures to prevent overheating.

  • The maximum allowable voltage drop across the input and output pins is 1V. Exceeding this limit may affect the device's performance, efficiency, and reliability.

  • Yes, the SW-328 can be used in a parallel configuration to increase output power. However, ensure that the devices are properly synchronized, and the output currents are balanced to prevent uneven stress and potential damage.

  • Stancor recommends using a pi-filter (L-C-L) configuration at the input and output to reduce EMI and noise. The filter components should be selected based on the specific application and operating frequency.
