I need a DC-DC converter prototype as per the following parameters: Power Rating: 150W Input: 16-32V DC Output: 5V, 25A Output Variation: 2-5V using a 10K Ohm External Pot Output Regulation: 3% Deliverables I expect • Schematic with clearly annotated component values • Bill of materials with manufacturer part numbers and current pricing • Simulation files (LTspice, PSpice or similar) showing efficiency, ripple and thermal figures under typical and worst-case loads • PCB layout in KiCad, Altium or another mainstream CAD tool, with fabrication-ready Gerbers • A concise design note explaining choices, expected performance and any tuning steps required during bring-up • A fully developed & fabricated prototype with functional demonstration (through live video). Acceptance criteria The converter must hold the specified output within the agreed tolerance across the full input range and load profile, maintain stable regulation without oscillation, and stay within its thermal limits during a 90-minute full-power test in simulation. If you have previous boards or test data that demonstrate similar performance, mention them when you respond so I can quickly see how your experience lines up with this brief.

Hi, I can handle this DC-DC buck converter design with your specified requirements (150W, 16–32V input, 5V/25A output, adjustable 2–5V via 10k pot, ~3% regulation). This is a standard high-current design and fully achievable with proper component selection and thermal design. I will provide the complete deliverables including schematic, BOM with manufacturer part numbers, simulation files (efficiency, ripple, thermal), PCB layout with Gerbers, and a concise design note. I can also support prototype fabrication and live functional demonstration. I have worked on similar high-current buck designs before, so I’m familiar with handling efficiency, stability, and thermal challenges at this power level. Best regards, Ahmed Yahia

Hello, I can take on this 150W DC-DC converter design and prototype. My approach: Topology: Synchronous buck converter (optimized for 16–32V → 5V @ 25A) Control: Current-mode PWM controller for tight load regulation and stability Adjustment: External 10k potentiometer implemented via feedback network (0–5V adjustable output range) Thermals: Designed with efficiency and heat distribution as a primary constraint (multi-phase or high-current single-phase depending on final trade-off) Deliverables: Full schematic with annotated values BOM with manufacturer part numbers Simulation (LTspice or similar) for: efficiency curve ripple performance thermal load approximation under full power PCB layout (KiCad or Altium) with production-ready Gerbers Short design note explaining key decisions + tuning procedure Assembled working prototype + validation testing Performance targets: 150W continuous output 16–32V input range stability 3% output regulation target maintained under load and line variation Stable operation under sustained full-load thermal conditions Timeline: Schematic + simulation: ~5–7 days PCB + BOM: ~5 days Prototype build/testing: ~1–2 weeks depending on parts availability I’ve designed high-current switching supplies and buck converters in the 100W–300W range before, including thermal-validated layouts for compact enclosures and high-efficiency synchronous designs, so this falls well within scope.
