Conclusion

While 48V systems can reduce weight and gauge of the wire harness, saving cost in the actual copper of the wire and in manufacturing, the conversation comes back to cost. The adoption of 48V has many benefits and challenges that will affect cost in some way, whether at the IC level or system level. OEMs will decide when and how to incorporate 48V systems to maximize benefits and reduce cost. The market and semiconductor suppliers are ready for 48V systems, as evidenced by recent vehicle innovations.
