I need a surface-mount power-supply board designed for a consumer-electronics product. The board will run directly from 220–260 V AC and must deliver a regulated 144 V DC at 300–350 mA. Reliability is critical, so the design has to meet a 6 kV surge requirement, include both high- and low-voltage protection, and achieve a high power factor. I already know the exact outer dimensions for the PCB and will forward the drawing as soon as we start; everything has to fit inside that footprint. Apart from those limits, component placement is up to you. I’m leaning toward standard FR-4, but I’m open to alternatives if you see a clear advantage. Please supply the complete schematic, PCB layout, Gerber files, an annotated BOM with part numbers available from major distributo...

I’m developing a compact, aluminium-clad SMD PCB that will live directly on mains, so every detail must be right first time. The board sits on 1 mm aluminium with 25 µm copper, accepts 220-260 VAC and has to deliver a rock-solid 144 VDC at 300-350 mA. Power-factor must stay high thanks to a hybrid DOB topology, while the protection network must survive 6 kV surges and automatically cut in on both high- and low-voltage events. Everything must be RoHS-compliant. Because the board ultimately feeds a power-supply module, thermals and creepage/clearance are just as critical as the electrical design. I’m looking for a clean, production-ready package that lets me hand Gerbers straight to my fabricator and have parts placed with confidence. Deliverables • Complete schema...

I need a complete engineering solution for an ultra-low-frequency electromagnetic transmitter that operates at roughly 22 Hz and fits inside an inline pipeline PIG.
