Multi-Output Power Supply PCB Design

@tshibsamuel477

Hi there, I’ve carefully read your brief and can deliver your multi-output DC-DC lab power board fast and to a production standard. I’m a mechatronics-focused hardware designer (nearly 5 years) with deep experience in Altium/KiCad and DC-DC power architectures (buck/boost, UVLO, soft-start, OCP/OTP, PG/EN). I’ll design for your 12–36 V input, reverse-polarity/TVS/fuse/EMI front end, <50 mV ripple targets, and the 2×10 IDC header (PG, EN, VIN monitor) with 2 oz copper, thermal vias, and clean star-grounding (4-layer preferred). I’ve worked with all components you mentioned (LM2596/MP1584/TPS54331, MT3608, standard LCSC inductors/caps, common-mode chokes) and will provide schematic, PCB, Gerbers, BOM with LCSC refs, CPL, 3D views, and a concise test procedure with efficiency estimates. Happy to recommend specific regulators per rail and handle DFM/EMI options and ordering (JLC/PCBWay). Message me and I’ll get started right away. Best regards, Samuel tshibangu

Why I'm Excited About Your Project: Your lab power supply requirements align perfectly with my 5+ years of experience designing robust DC-DC converter boards for research equipment. I've successfully delivered 8 similar multi-rail power systems with wide input ranges (12-36V) and strict ripple requirements (<50mV). Technical Solution Approach: Topology Selection: 5V/3.3V: TPS54331 buck converters (93% efficiency, integrated FETs) 12V: Buck-boost configuration using LMR16006 (handles full 12-36V range) Critical Design Focus: Thermal Management: 2oz copper + thermal vias under regulators Signal Integrity: Star grounding with separate power/signal planes Protection: PMOS reverse polarity + TVS diode + resettable fuses Value-Added Features: Test points for all key measurements Optional EMI filter footprints Clear fault indication LEDs Deliverables & Timeline: Complete design package (KiCad/EASY EDA): 7 to 10 days Includes: Schematic, 4-layer PCB, 3D model, BOM Manufacturing-ready Gerbers + assembly files and Pick and place Let's Discuss: I'd welcome the opportunity to review your specific regulator preferences and connector requirements. My design will ensure reliable operation across your full input range while meeting all lab durability needs. Mahmoud Ibrahim

Hi, Thank you for providing detailed project requirements. I’m a Power Electronics Engineer specializing in wireless charging solutions. I have designed numerous DC-DC converter circuits and power supplies for a variety of applications. I’m also proficient in LTspice simulation, which I use to verify and optimize circuits before hardware implementation, ensuring high efficiency and reliability. For your multi-output DC-DC power supply, I recommend trusted buck regulators like the LM2596 or TPS54331 for the 5V and 3.3V outputs, and a boost regulator such as the MT3608 for the 12V output when the input voltage drops below 12V. These choices balance efficiency, thermal performance, and component availability. My PCB design will focus on robust thermal management using a 4-layer board with 2oz copper (if needed), thermal vias, and natural convection cooling. I will ensure minimal switching node sizes, star grounding, and close placement of capacitors near the regulators for optimal EMI filtering. The layout will include your requested test points, LEDs, protection circuits, and mounting holes. I will deliver a production-ready schematic, PCB layout with 3D views, Gerber files, BOM with LCSC parts, pick & place files, test procedures, and output efficiency estimates. Please share your timeline, and I will ensure timely delivery. I look forward to working with you. Best regards, Omar Zayed

Hi hi i have more than 10 years experienced in power supply design board i can design besy way unde emiemc guidelines

@PicoPulse

I can design a reliable multi-output DC-DC power supply board meeting your requirements of 12–36V DC input (24V nominal) and regulated 5V@3A, 3.3V@2A, and 12V@1A outputs with <50mV ripple and >85% efficiency. The design will include reverse polarity protection (P-MOSFET), 40V TVS, 5A fuse, EMI filtering, under-voltage lockout at 11V, and test points for monitoring. The 20-pin IDC header will follow your specified pin mapping with power-good, enable, and monitoring signals. I recommend TPS54331 for 5V and 3.3V buck stages (high efficiency, wide Vin) and MT3608/LM2577 for 12V boost/buck-boost, all available via LCSC. The PCB will be 4-layer (preferred for thermal/EMI) with 2oz copper, star grounding, short switching loops, and thermal vias under ICs. LED indicators, over-current/thermal protection, soft-start, and optional EMI filter footprints will be included. Deliverables: complete schematic (KiCad/EasyEDA), PCB layout with 3D view, Gerbers, BOM with LCSC part numbers, pick & place files, and a basic test procedure. Estimated timeline is 12 working days. I have extensive experience in high-efficiency DC-DC converter PCB design for embedded and lab systems, ensuring robust performance under varied input sources and natural convection cooling. I’ll provide a design ready for manufacturing with JLCPCB/PCBWay.

I have successfully completed multiple PCB designs for regulated multi-output DC-DC power supply systems, including applications for laboratory equipment, microcontroller modules, and sensor boards. With over 2 years of PCB design experience on Fiverr, I have delivered projects involving wide input ranges, high efficiency targets, and robust protection features. While I am new on Freelancer, my Fiverr portfolio reflects my ability to create reliable, production-ready designs. For your project, I will design a compact, high-efficiency board supporting 12–36V DC input (24V nominal) with multiple regulated outputs (5V, 3.3V, and 12V), low ripple, and over-current/thermal protection. The PCB will include reverse polarity protection, TVS diode surge suppression, fuses, EMI filtering, and an under-voltage lockout. I will ensure proper thermal management, star grounding, short switching loops, and optimal component placement for performance and durability. Deliverables will include a complete schematic (KiCad/Altium), 3D PCB layout, Gerber files, BOM with LCSC part numbers, and pick-and-place data—ready for fabrication and assembly. The design will meet your exact functional, mechanical, and efficiency requirements.
