Frequently Asked Questions

What are the benefits of 48V direct conversion vs 12V intermediate bus?

48V direct conversion eliminates the 12V intermediate bus stage, improving efficiency by 3-5% and reducing power distribution losses. Benefits include: 1) Higher efficiency - one less conversion stage. 2) Reduced busbar copper - lower current at higher voltage. 3) Smaller PCB area - fewer components. 4) Better transient response - direct conversion to load. MPS offers 48V-to-point-of-load converters for next-generation data center architectures.

Consider 48V architecture for new designs. Contact us for 48V power solution recommendations.

How do I optimize for light-load efficiency?

Data center servers spend significant time at light load. Optimization strategies: 1) Use converters with automatic PFM/PWM mode switching. 2) Implement phase shedding in multi-phase designs. 3) Optimize switching frequency for load range. 4) Use synchronous rectification with proper gate drive. 5) Minimize quiescent current. MPS converters feature advanced light-load optimization maintaining >90% efficiency at 10% load.
