Hey — I’m ready to take this on. A 150 W adjustable DC-DC converter isn’t about copying an app note; it’s about topology selection, loop compensation, thermal margins, and layout discipline so it stays stable and cool across the full input range. This is exactly where I’m different from most bids you’ll get here. I’m a seasoned power-electronics engineer, not a middleman. I’ve designed and built 100–300 W buck and buck-boost converters with wide input ranges, adjustable outputs, and proven thermal performance. I have a solid track record of delivering converters that regulate cleanly, simulate accurately, and behave the same way on the benches. You can visit my profile to see what past clients say about my work. If this sounds like a good fit, let's start a conversation in the inbox using the chat button below, and we can quickly align on preferred controller ICs, efficiency targets, and prototype logistics. Looking forward to it. Abbas Jawad Wala SMB ElectroTech P.S. I take on selected projects only, especially power designs where mistakes are costly. If you want a converter that simulates, builds, and performs as specified, this is exactly my wheelhouse.

LI can design and prototype a 150 W high-current DC-DC converter (16–32 V in, 2–5 V up to 30 A out) with stable regulation, thermal robustness, and adjustable output via external pot. I’ll deliver a fully documented schematic, BOM with pricing, validated simulations, production-ready PCB, and a fabricated prototype demonstrated live. I have prior experience with high-power SMPS and DC-DC designs delivering similar current and efficiency levels. Note Estimated Bid price not included components procurement PCB Fabrication and Assembly.

Thank you for the detailed and challenging 150W DC-DC converter requirements. This project demands careful topology selection and thermal management to achieve 30A at 5V efficiently. I propose a synchronous buck converter using a robust, multi-phase controller (e.g., from TI or Monolithic Power) to distribute the high output current, minimize inductor size, and improve thermal performance. The design will include precise current sensing, input/output filtering, and the specified 10kΩ potentiometer for adjustable output. I will deliver a complete engineering package: the annotated schematic, a BOM with sourced parts, a KiCad PCB layout optimized for high-current traces and thermal dissipation, and LTspice simulation files validating efficiency (>90% target), output ripple (<50mV), and thermal stability. The design note will detail component selection, control loop compensation, and bring-up tuning procedures. Upon approval of the design, I will oversee the fabrication and assembly of a functional prototype, providing a live video demonstration under full load across the input voltage range. I have successfully delivered similar high-density power supplies and can share simulation results and board images from a recent 100W, 20A synchronous buck project.
