📊 Typical Specifications
Parameter Specification (typical)
Input Voltage Range 10 V – 32 V DC
Output Voltage Range 12 V – 35 V DC (adjustable)
Maximum Output Current 6 A
Maximum Output Power ~150 W (with enhanced cooling)
Input Current (Max) ~10 A (depends on Vin/Vout)
Conversion Efficiency Up to ~94 % (varies with load & voltages)
Output Ripple ~2 % (max)
Voltage & Load Regulation ± 0.5 % typical
No‑Load Current ~25 mA typical
Operating Temperature ~–40 °C to +85 °C (industrial)
Protection No built‑in short‑circuit or reverse‑polarity protection (add external fuse/diode)
Module Size ~65 × 35 × 21 mm (varies)
Note: Output power around 150 W typically requires additional cooling (heatsinks or airflow). Without active cooling, many modules are rated closer to ~100 W.
🔌 How It Works
A boost converter (step‑up converter) increases (boosts) DC voltage: the output voltage is always higher than the input voltage. These modules use high‑frequency switching and energy storage components (inductor, diode, capacitors) to perform efficient DC‑to‑DC conversion.
VIN+ / VIN‑: input DC supply connections (10 – 32 V).
VOUT+ / VOUT‑: output boosted voltage (12 – 35 V) terminals.
Potentiometer(s): onboard trimmers adjust the output voltage.
No integrated protections → you should use an external fuse and diode at input for safety.
🔧 Typical Use Cases
✔ Running higher‑voltage electronics from a 12 V (car/battery) source
✔ Powering 24 V devices using a 12 V input
✔ DIY adjustable power supplies
✔ Boosting solar panel or battery voltages
✔ Driving amplifiers, robotics motors, LED lighting (within limits)
⚠️ Safety & Best Practices
Cooling: At higher currents near 6 A or high output voltages, heat can build up — adding a heatsink or airflow helps reliability.
Protection: These cheap modules often lack short‑circuit or reverse‑polarity protection. Add a fuse and/or series diode at the input.
Adjust Before Load: Use a multimeter to set output voltage before connecting sensitive devices.
Power Limits: At higher boost ratios (e.g., 12 V→35 V), available current and power may be lower than the ~150 W rating.
