Subject: High-Reliability 5V/60A Design: Solving the Thermal & Ripple Bottleneck Hi, 60A at 5V is a brutal load for any video wall. Most designers fail here because they treat it like a standard 12V rail, resulting in overheated PCBs and visible ghosting on the panels. I will solve this with a 4-layer heavy-copper architecture designed for 24/7 industrial stress. My Technical Strategy: 1. Thermal Management: I'll replace standard diodes with Synchronous Rectification (4x Infineon OptiMOS <0.8mΩ). At this current, it’s the difference between 30W of wasted heat and a cool, stable board. 2. Signal Integrity: Using a 4-layer stackup with dedicated Power/GND planes, I’ll eliminate the parasitic inductance that causes flicker during 0-100% brightness transients. 3. Automated Production: No manual winding or "hand-made" transformers. I implement SMT Planar magnetics and molded IHLP inductors, making the design 100% ready for high-speed SMT assembly lines. 4. Compliance: Active PFC (85-265V) and Class B EMI filtering are integrated to ensure global market readiness. You get a professional Autodesk Eagle package: Schematics, Gerbers, and a vetted BOM optimized for Chinese PCBA sourcing. If you need a "set and forget" power stage that won't fail in the field, let’s talk. I can have the architecture mapped out immediately.

I have extensive experience designing high-power SMPS solutions, including a 5V 60A power supply for LED display applications with efficiency above 92% and ripple below 50mVp-p. In a recent project, I developed a 300W, universal input power supply with comprehensive EMI/EMC compliance, thermal management, and protective features such as OVP, OCP, and OTP, ensuring 24/7 reliable operation. My approach includes optimized PCB layout for minimal noise, robust transformer design tailored for high current, and control circuitry that maintains stable voltage and current under varying load conditions—validated through extensive testing and simulation data. Would you require the parallel operation capability to be integrated now, or as a future upgrade? I will do my utmost to deliver a fully compliant, reliable, and efficient solution that meets your specifications and project goals.

I designed 3kw charger as my recent project. I have 5 year of experience in smps design and worked on various topologies. For your case we can go with flyback as a option . Low cost and around 80% efficiency. I will also take care of thermal related issues and voltage ripple of 4-5% and current ripple of 15-25% .
