Infineon expanded its existing collaboration with Delta Electronics to develop state-of-the-art vertical power delivery (VPD) modules that can supply power to AI chips in data centers more efficiently. These losses add up even over short distances due to the ultra-high currents used by high-performance AI chips. Vertical vs. Lateral Power DeliveryInfineon and Delta are trying to cut through these challenges by replacing lateral with vertical power delivery. Delta is developing vertical power modules with Infineon's silicon OptiMOS integrated power-stage solution. The tech is a boon to vertical power delivery because it underpins Infineon’s vertical trench MOSFETs, which allows for a closer connection to GPUs or other AI chips.
