Product Overview
The 600W 10A High-Power DC-DC Boost Converter Module is a professional-grade step-up switching regulator designed to convert lower DC voltages into higher, adjustable output voltages. Whether you need to power a laptop from a 12V car battery, drive high-power LED arrays, create a custom benchtop power supply, or charge lithium battery packs, this module delivers the performance and flexibility required for demanding applications.
At its core, this module utilizes a non-isolated boost (BOOST) topology with a maximum input current of 15A and a maximum output power of up to 600W. The input voltage range of 10V to 60V allows it to accept power from a wide variety of sources, including 12V car batteries, 24V truck electrical systems, solar panels, and 36V industrial power rails. The output is continuously adjustable from 12V to 80V, making it suitable for everything from charging lithium battery packs to powering 80V LED lighting systems.
A standout feature of this module is its dual-mode operation: it functions as both a constant voltage (CV) power supply and a constant current (CC) LED driver. The onboard potentiometers allow you to independently set the output voltage and current limit, making it perfect for charging batteries (where a constant current/constant voltage profile is required) and driving high-power LEDs (where a regulated current is essential to prevent thermal runaway).
The module achieves a conversion efficiency of up to 95% thanks to its 150kHz switching frequency and high-quality components, including a toroidal inductor and low-ESR capacitors. For enhanced durability, the module is built with an aluminum PCB substrate, which acts as a heatsink to dissipate heat during high-power operation. Some versions also include a cooling fan for active thermal management.

Wiring Instructions
IMPORTANT: Always disconnect the input power source before wiring or modifying connections. Double-check polarity to avoid damage.
Basic Connection (CV Mode – Powering a Device)
-
Connect Input: Connect the positive wire of your DC power source to the IN+ terminal. Connect the negative wire to the IN- terminal.
-
Set Initial Voltage: Before connecting your load, turn the CV-ADJ potentiometer fully counter-clockwise (minimum voltage). Turn the CC-ADJ potentiometer fully clockwise (maximum current limit).
-
Power On & Adjust Voltage: Apply power. Use a multimeter on the output terminals. Slowly turn the CV-ADJ potentiometer clockwise until you reach your desired output voltage (e.g., 19V for a laptop).
-
Connect Load: Turn off power, connect your device to OUT+ and OUT-, and re-apply power.
Constant Current (CC) Mode – Driving High-Power LEDs
-
Set Desired Output Voltage: Determine the forward voltage of your LED array (e.g., 10x LEDs in series = 37V). Follow the steps above to set the output voltage to this value using the CV-ADJ potentiometer.
-
Set Current Limit: Turn the CC-ADJ potentiometer counter-clockwise about 20-30 turns to set the current to minimum.
-
Connect LED Load: With power OFF, connect your LED array to the output terminals.
-
Adjust Current: Apply power. Slowly turn the CC-ADJ potentiometer clockwise while monitoring the current with a multimeter in series with the LED. Stop when you reach the desired drive current (e.g., 5A for a high-power LED).
Important Notes for Current Adjustment
-
Do NOT short the output to adjust current. The boost converter circuit cannot adjust current in a short-circuit condition. Always connect a load (LED, discharged battery) when setting the constant current limit.
-
For battery charging, use a fully discharged battery to set the current limit. If the battery is partially charged, it will draw less current, making it difficult to set the limit accurately.
Parallel Operation for Higher Current
If you need more than 10A output current, you can connect two modules in parallel (inputs together, outputs together). Adjust each module’s current limit to share the load equally (e.g., set each for 8A if a total of 16A is needed).

Important Considerations
-
Heat Management: This module can get hot under high load (>400W). At currents above 6A-8A, a heatsink or fan is mandatory.
-
Power Derating: The maximum achievable output power depends on input voltage and current. For example: Input 12V × 10A = 120W max output; Input 24V × 10A = 240W max output; Input 48V × 10A = 480W max output; Input 60V × 10A = 600W max output.
-
Wire Gauge: Use appropriately thick wire (14-16 AWG or thicker) for both input and output connections to minimize voltage drop and overheating.
-
Input Source Capability: Ensure your input power source can supply enough current. When boosting voltage, the input current is higher than the output current (Power In = Power Out / Efficiency).
-
Voltage Differential: The maximum output current is inversely related to the input-output voltage difference. The larger the voltage difference, the smaller the achievable output current.
Q: What is the difference between a boost converter and a buck converter?
A boost converter (step-up) increases a lower input voltage to a higher output voltage (e.g., 12V to 24V). A buck converter (step-down) decreases a higher input voltage to a lower output voltage (e.g., 24V to 12V). This module is a boost converter only
Q: What is the maximum output voltage and current?
The maximum output voltage is 80V. The maximum output current is 10A, but this is dependent on the input-output voltage differential. The larger the voltage difference, the smaller the achievable output current. Above 6A, a heatsink or fan is required
Q: Can I use this module to charge a battery?
Yes. The module’s constant current/constant voltage (CV/CC) mode is ideal for charging lithium-ion, LiFePO4, and lead-acid batteries. Set the output voltage to the battery’s float voltage, and set the current limit to the desired charge current. The module includes output anti-backflow protection for charging applications
Q: What is the difference between the two potentiometers (CV-ADJ and CC-ADJ)?
CV-ADJ controls the output voltage (CV mode). CC-ADJ controls the output current limit (CC mode). For standard voltage regulation, set CC-ADJ to maximum (fully clockwise). For LED driving or battery charging, use CC-ADJ to set the maximum current
Q: Does this module have reverse polarity protection?
No. The module does not include input reverse polarity protection. If you need this feature, add an external diode in series with the input positive line
Q: Why can't I get 600W of output power?
600W is the theoretical maximum under ideal conditions. The actual achievable power depends on your input voltage and current. The module’s output power is limited by the input power: P_out = V_in × I_in × Efficiency. For example, at 12V input with 10A, the maximum output is approximately 120W
Q: The module gets very hot. Is this normal?
At high power levels (>300W), the module will generate significant heat. The aluminum PCB is designed to act as a heatsink, but for continuous operation above 400W-500W, an external cooling fan or larger heatsink attached to the backplate is necessary
Q: How do I set the constant current (CC) limit correctly?
To set the CC limit, you must have a load connected. For LED driving, connect the LED. For battery charging, use a discharged battery. Do not attempt to set the current by shorting the output, as this can damage the module
Q: What is the quiescent current (idle power consumption)?
When the module is powered but no load is connected, it draws approximately 10mA-15mA (at 12V input). This may increase slightly at higher output voltage settings
Q: Can I use two modules in parallel for more power?
Yes. For applications requiring more than 10A, you can connect two modules in parallel (inputs together, outputs together). Adjust each module’s current limit to share the load equally (e.g., set each for 8A if total needed is 16A)
Q: The module is not working. The output voltage is 0V.
Follow this checklist:
-
Check input power supply voltage (must be above 10V).
-
Check polarity (IN+ to positive, IN- to negative). Reverse polarity may have damaged the module.
-
Check that the CV-ADJ potentiometer is not turned fully counter-clockwise (minimum voltage).
-
Check the input fuse (if present). Replace if blown
Q: The output voltage is fluctuating or unstable.
This can be caused by:
-
An unstable or insufficient input power supply (voltage sag under load).
-
Overheating (thermal protection may be throttling output).
-
Loose connections or insufficient wire gauge.
-
The load may be exceeding the current limit setting.
Q: Is this module suitable for powering sensitive electronics?
The module has output ripple typical of high-power switching converters. For extremely sensitive electronics, additional output filtering (e.g., an LC filter) may be required to reduce high-frequency switching noise.
Q: Why is my measured output current lower than the set value?
This can happen if:
-
The load resistance is too high (the module is in CV mode, not CC mode).
-
The input power source cannot supply enough current.
-
The input voltage is too low to maintain the desired output power.
