🔋 200 W DC-DC Synchronous Buck Converter — 8–55 V In → 1–36 V Out, up to 15 A

High-efficiency, low-ripple step-down module with an aluminum shell and screw terminals. Ideal for car/RV systems, LED strips, radios, test benches, CNC/3D-printer accessories, and battery-powered projects.

🌟 Highlights

• 🌐 Wide Input: 8–55 V DC (absolute max 60 V — leave margin)

• 🎛 Continuously Adjustable Output: 1–36 V (default ≈ 12 V)

• ⚡ High Current Capability: 10 A continuous (typical), 15 A peak

• 🧊 Aluminum Housing: Better heat spread; screw terminals for secure wiring

• 🔄 Synchronous Design: Up to 94% efficiency with low ripple

• 🛡 Protections: Over-current sampling at ~15 A, reverse-polarity input protection

Buck only: Output must be lower than input (allow ≥0.8–1.5 V headroom under load).

• Reverse-polarity (input): Yes

• Terminals: High-current screw posts (no soldering)

🔌 Wiring

• IN+ / IN− → DC input supply (observe polarity)

• OUT+ / OUT− → DC load

• Use adequate wire gauge for the expected current; tighten terminals firmly.

🧠 Performance & Safety Tips

• For long sessions, keep load to ≤80% of the thermal limit (e.g., ≤8 A or ≤100 W without extra cooling).

• Add heatsinking or a small fan for higher power (150–200 W).

• Do not short the output. Power up with the load connected and adjust voltage slowly.

• This is a DC module (no AC).

• If feeding sensitive electronics, verify ripple and voltage with a DMM/scope before final hookup.
