Power Supply Unit (PSU)

Empower your High-Density 48V AI PSU designs.

The transition to extreme-density AI data centers requires ultra-efficient power conversion at the rack level. When engineering a high-density AI PSU, minimizing switching losses and maximizing thermal performance across both the front-end AC/DC Power Factor Correction (PFC) and the downstream DC/DC stages is critical. Allegro provides the advanced semiconductor portfolio needed to optimize these next-generation power supply units, enabling superior efficiency, safety, and power delivery through: ·         

• Precise Power Monitoring: High-bandwidth XtremeSense™ TMR current and Hall based sensors that deliver highly accurate real-time telemetry and nanosecond fault protection.
• High-Density DC/DC Conversion: Power-Thru™ isolated gate drivers that unlock wide-bandgap performance, delivering up to 10x lower common-mode capacitance to shrink system footprint and mitigate EMI.
• Intelligent Thermal Management: Code-free 48V motor drivers featuring QuietMotion™ Field-Oriented Control (FOC) for highly efficient, whisper-quiet cooling fan operation.
