Using the UCC28880 FET integrated buck controller, this design provides a universal line to non-isolated 3.3 V/30 mA for arc fault and ground fault circuit Interrupter circuit breaker systems. This tiny design is built on a single-layer PCB in a space optimized 0.680" by 0.480" footprint by implementing a half-bridge rectifier and not requiring a large transformer.
