Non-isolated power architecture with diagnostics reference design for protection relay modules
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.
