Dual DC Output PCB Design

@AlexandrGergel

Greetings, I’ve worked on embedded hardware where power integrity, protection, thermal limits, and PCB layout were important, including custom boards with switching regulators, mixed-signal sections, and tight mechanical constraints. I normally review the power tree first, select parts with enough margin, then check schematic, layout, BOM, and fabrication files together instead of treating them as separate steps. For these two boards, I think the main challenge will be keeping ripple and temperature under control inside the custom enclosure while still meeting EMI/EMC needs, so I would first build the loss and thermal budget, simulate the critical stages, and then design the copper and component placement around those results. Once the exact input/output voltage and current ratings are available, I should be able to provide the first schematic/design review in around 1 week and then estimate the full PCB schedule accurately. Sincerely, Oleksandr

Hi, I am an embedded systems engineer with over 16 years of experience designing reliable power electronics and complete consumer- and industrial-grade products from concept through production. I have extensive experience with regulated DC supplies, low-ripple power design, protection circuits, thermal analysis, EMI/EMC-aware PCB layout, and fabrication-ready documentation. I can develop both custom-sized boards from schematic through simulation and PCB layout, accounting for the mechanical envelope, mounting points, copper weight, component availability, and safe thermal margins. I will provide native Altium, KiCad, or Eagle files, Gerbers, drill files, and a detailed BOM with manufacturer part numbers. The designs will include over-voltage, over-current, and reverse-polarity protection, with attention to ripple, efficiency, load transients, and temperature rise. I will also support one review pass after first-article testing and can assist with firmware or system integration if needed. Please share the input-voltage range, output voltage/current required for each board, ripple target, cooling conditions, and mechanical drawings. Please contact me to discuss details.

Hi, I understand you need two reliable DC power supply PCBs with different power ratings, low ripple, and stable output for industrial equipment. I can take your electrical requirements and custom mechanical constraints from schematic design through fabrication-ready PCB files. I will select suitable power-stage components with proper over-voltage, over-current, reverse-polarity, and thermal protection. The designs will be optimized for regulation, efficiency, low ripple, thermal performance, and stable operation under load changes. I will simulate the critical power sections and check component stress, efficiency, load-step response, and expected temperature rise. For the PCB layout, I will focus on short current loops, proper grounding, copper distribution, thermal paths, and EMI/EMC practices. I can work in Altium Designer and provide the native design files along with Gerbers, drill files, and complete BOM. The BOM will include manufacturer part numbers and suitable alternatives to help avoid component availability issues. I have 10+ years of experience in power electronics, industrial PCB design, and reliable hardware development. After fabrication, I can review your first-article test results and handle the required design adjustments in the review pass. Send me the input/output ratings and mechanical drawing, and I can start by defining the power architecture for both boards.

Please share more details about the input/out, current rating, ripple/noise specs, what are the machanical constraints. how you want the protections as well as expected efficiency. I will use KiCad and will share the design files and Gerber as well as BOM/CPL files.

@markoa7

Your request for two independent DC-supply PCBs with bespoke dimensions and low ripple aligns with my recent dual-output designs. I recently delivered a dual-output board achieving <20 mV RMS ripple and stable regulation at 5 A per rail. - Translate specs into clean schematics in Altium or KiCad, run simulations for regulation, efficiency, and thermal behavior. - Layout with EMI/EMC discipline, adequate copper weight, separation, and robust protection (OVP, OCP, reverse polarity); one quick review after first-article test data. - Portfolio reference: https://www.freelancer.com/u/markoa7 What are the exact ripple, load-step, and temperature targets for each output, and how strict must the EMI/EMC performance be in your assembly environment? Happy to hop on a quick call to discuss Marko Aleksic

Hi, This is a strong match for my background. I currently work for a US-based robotics company, designing electronics for compact robotic systems where reliability, power integrity, EMI/EMC, and mechanical constraints are critical. I normally start with SPICE simulation to validate the power topology and component selection, including regulation, transient response, efficiency, and component stresses. One of my strongest areas is EMI/EMC-aware PCB layout. I pay close attention to high-frequency switching paths and return paths, minimizing high di/dt loop areas, parasitic inductance, and unwanted coupling. I carefully optimize switching nodes, capacitor loops, grounding, feedback, and sensitive signal routing. I also really enjoy compact PCB design and challenging mechanical constraints. In robotics, I frequently work with tight size limitations and irregular PCB shapes following the enclosure, rather than standard rectangular boards. I can handle the complete design from SPICE → schematic → PCB layout → manufacturing, including protection circuits, copper sizing, thermal considerations, complete BOM, native Altium/KiCad files, Gerbers, and drill files. I can also support one review/update pass after first-article testing. Best regards, Hendra

Hello, Designing custom-fit, low-ripple industrial power supplies requires careful balance between thermal management, tight voltage regulation, and robust EMI/EMC layout practice. As an Electronics Engineer specializing in power electronics, I can deliver both bespoke DC-supply PCBs fully optimized for your mechanical enclosure. How I Will Approach Your Power Supplies: Schematic & Protections: Engineer clean regulation topologies (Buck/Boost/Linear) featuring integrated over-voltage (TVS), over-current (PTC/Sense), thermal shutdown, and reverse-polarity protection. Simulation & Thermal Analysis: Run SPICE/Simulink simulations to verify load-step response, ripple suppression, and thermal dissipation prior to layout. Custom Enclosure PCB Layout: Designed in Altium Designer (or KiCad) using heavy copper fills, optimized current-loop areas, and strict noisy-to-quiet ground separation to fit your exact mounting envelope. Manufacturing Package: Native source files, production Gerbers, drill files, and an annotated BOM with active, globally stocked parts. Post-Fab Support: Includes a full design review pass and post-fabrication support based on your first-article test data to fine-tune regulation or thermal performance. I am ready to review your mechanical envelopes, power targets, and ripple specifications to begin immediately. Best regards,
