⚡ 400W DC-DC Step-Up Boost Converter — CC/CV • 8.5–50 V In → 10–60 V Out • up to 12 A

High-efficiency booster for laptops, LED arrays, battery charging, bench power, and solar panel regulation. Screw terminals for easy wiring and dual heatsinks for better thermal performance.

🌟 Highlights

• 🔺 Step-Up (Boost) Topology: raise DC input to a higher DC output

• 🎛 CC/CV control: constant-voltage and constant-current modes (ideal for LED driving & battery charging)

• ⚙️ High efficiency: up to 96% (depends on Vin/Vout/ΔV and load)

• 🔧 Tool-less wiring: large screw terminals for input/output

• 🧊 Thermal design: two heatsinks; add airflow for heavy loads

📐 Specifications

• Type: Non-isolated boost converter

• Input: 8.5 – 50 V DC (observe polarity)

• Output: 10 – 60 V DC, continuously adjustable (default ≈ 19 V)

• Max Input Current: 15 A (add cooling above ~8 A)

• Max Output Current: 12 A*

• Constant-Current Range: 0.2 – 12 A

• Quiescent Current: ≈ 10 mA (higher when boosting 12 → 20 V)

• Switching Frequency: ~150 kHz

• Efficiency: up to 96%

• Operating Temp: −40 °C to +85 °C (derate or add cooling at high load)

• Protection: Input over-current limiting (~15 A → reduces Vout)

• Reverse Input Protection: No (use a series diode or MOSFET if needed)

• Size: 67 × 47 × 27 mm (2.64 × 1.85 × 1.06 in)

*Output current depends on the voltage step-up ratio. The larger the ΔV, the lower the sustainable output current. Always keep Pout ≤ Vin × Iin × efficiency and provide cooling.

🔌 Quick Wiring

• VIN+ / VIN−: DC input source (battery, PSU, solar panel)

• VOUT+ / VOUT−: Load (laptop, LED array, charger input, etc.)

• Use thick, short wires for high current.

🎚️ Adjustment Guide (CC/CV)

1. Preset CC to minimum: Turn CC-ADJ counter-clockwise ~30 turns.

2. Set CV (voltage): Power module, no load. Turn CV-ADJ

   • Clockwise = higher Vout, counter-clockwise = lower Vout.

3. Set CC (current limit):

   • Connect load (or short via ammeter for setup).

   • Turn CC-ADJ clockwise until desired current is reached.

   • In use, when load tries to draw more, module enters constant-current (voltage sags accordingly).

Battery charging tip: Set CV to float/target voltage of the chemistry; set CC to the safe charge current. Connect the discharged battery first for correct current limiting.

🧠 Application Notes

• For high-power LED arrays, operate in CC with CV as a ceiling.

• With solar input, ensure panel Voc < 50 V and use CC/CV to prevent overload; this is not an MPPT controller, but works well as a post-regulator.

• Add a fuse on the input and provide forced air cooling for >7–8 A output.

• No reverse-polarity protection—add a diode or ideal-diode if your source can be connected backwards.

• Do not exceed component ratings. Enclose to avoid accidental shorts.
