EnaChip

EnaChip is a developer of wafer-level magnetic technology for semiconductor power delivery. It develops electroplated magnetic alloys with higher resistivity and high flux density, enabling operation at significantly higher frequencies while suppressing eddy current losses, and replaces sputtering with a continuous electroplating process so that what previously required 70+ steps can now be achieved in ~5 steps with a single mask.

The magnetics integrate with high-frequency switches, including GaN and advanced silicon. Multilayer magnetics suppress core loss at high switching frequencies, allowing the devices to shrink for low-inductance designs. EnaChip targets AI data centers, where only 44% of power entering reaches the chip, with the largest loss occurring in the last few centimeters between the regulator and the die.
