This reference design showcases non-isolated power supply architectures for protection relays with analog input/output and communication modules generated from 5-, 12-, or 24-V DC input. To generate the power supplies the design uses DC/DC converters with an integrated FET, a power module with an integrated inductor for size- and design-time-constrained applications, a HotRod™ package type for applications requiring low EMI and linear regulators (LDOs) for low ripple. Protections include a flat clamp TVS for input transient protection, an eFuse with configurable load current for overload protection and an ideal diode controller for input reversal protection. Additional features include an auto-switching power MUX, an analog temperature sensor, an input OK indication, a “no load” detection and a voltage supervisor.
