Server

As AI computing continues to scale rapidly, power consumption and thermal loads are rising in tandem. Because excessive heat degrades chip performance and system stability, optimizing power conversion and thermal management has become essential. Transitioning from 12V to 48V power architectures minimizes current losses at equivalent power levels, boosting motor efficiency and lowering coil temperatures. This transition effectively enhances motor performance and it is widely regarded as one of the most effective pathways to improving overall system efficiency.

To address the space constraints within servers, inergy has introduced the iU6398 three-phase motor control solution. It highly integrates a motor controller, three-phase gate drivers, an HV Buck controller, and an LDO into a compact QFN 4x4 package. Designed for 12V to 80V brushless DC motor applications — such as fans and pumps — the iU6398 delivers a streamlined and efficient drive solution.

Product Key Features:

High Integration

• • Three-Phase Gate Drivers: Supports N-channel MOSFETs up to 160V.
