Figure 1: A hybrid combination of a PMIC and discretes could give the optimal balance of size, cost and performance

System power management ICs (PMIC) integrate all or almost all of the required power rails, however, individual power rails are implemented using discrete dc/dc and LDOs. The best approach will depend on particular use cases and each users’ criteria. PMICs tend to offer better performance and controllability in

Figure 1: Redundant operation, basic star wiring options

A single power supply is most of the time sufficient in applications connected to an AC power source. However, there are sometimes additional boundaries set to fulfill either higher power needs, system reliability, or even mechanical constraints. The connection of two or more power supplies for redundancy is im
