Frequently Asked Questions

How do I protect against industrial voltage transients?

Industrial systems require protection against voltage surges and transients. Recommended protection: 1) Input fuse for overcurrent protection. 2) TVS diode (e.g., SMAJ series) for surge suppression. 3) Input capacitor (100µF+) for holdup during dips. 4) Common-mode choke for conducted EMI. 5) Reverse polarity protection diode. MPS converters have built-in UVLO and OVP, but external protection is essential for industrial environments.

Contact our FAE team for industrial protection circuit design and component selection.

What layout considerations are important for industrial power?

Industrial power layout best practices: 1) Minimize switching loop area to reduce EMI. 2) Use solid ground planes with minimal splits. 3) Place input capacitors close to VIN pins. 4) Use multiple vias for high-current paths. 5) Keep sensitive analog traces away from switching nodes. 6) Implement proper thermal vias under power ICs. 7) Use 4-layer boards for better noise immunity.
