While swapping the board is an option, repairing the existing board is often more cost-effective and educational. The schematic diagram is the roadmap of the board. It allows you to:
| # | Recommendation | Rationale | Impact | |---|----------------|-----------|--------| | 1 | Add a TVS diode across the input DC bus (e.g., SMAJ58A) | Protects against transients from the mains filter. | Increases robustness, negligible cost. | | 2 | Increase decoupling near the MCU (2 × 0.1 µF + 1 × 10 µF) | Improves supply stability during high‑frequency switching. | Reduces risk of brown‑out / jitter. | | 3 | Re‑size shunt resistor to 0.01 Ω (instead of 0.02 Ω) for better current resolution. | Improves measurement accuracy while keeping dissipation ≤ 0.2 W at 2 A. | Better control loop performance. | | 4 | Thermal pad on MOSFET Q3 and attach a low‑profile heatsink. | Current simulations show 5 W average dissipation at 50 % load. | Keeps junction temperature < 125 °C. | | 5 | Route high‑current traces with ≥ 2 mm width (or copper weight 2 oz). | To keep trace resistance < 10 mΩ and avoid hot‑spots. | Improves reliability. | | 6 | Perform a design‑for‑test (DFT) insertion point for a current‑sense amplifier. | Enables in‑situ verification of OCP thresholds. | Simplifies validation. |
