250W 10A DC-DC Step-Up Boost Constant Current LED Driver Power Module

250W 10A DC-DC Step-Up Boost Constant Current LED Driver Power Module is a high-power non-isolated step-up (boost) CC/CV converter built directly on a thermally conductive aluminum-core substrate PCB. Accepting 10V to 40V DC input and delivering an adjustable 10V to 50V DC output alongside an adjustable 0.2A to 6A (10A peak) constant-current limit, its aluminum baseplate acts as an integrated heatsink for driving high-wattage COB LED arrays, boosting solar panels, and charging 12V–48V battery packs.

Key Features:

• Direct Aluminum-Core Heatsink Substrate: Power MOSFET, Schottky rectifier diode, and double-wound pure copper Sendust toroidal inductor are mounted on an aluminum PCB baseplate for superior thermal transfer.
• Dual CC / CV Multi-Turn Precision Control: Independent 3296W multi-turn potentiometers regulate both Constant Voltage (10V–50V) and Constant Current (0.2A–6A) with <1% temperature drift.
• High 92%–96% Conversion Efficiency: Large Sendust magnetic core and dual-strand copper windings minimize core losses at 150kHz switching frequency.
• Input Reverse-Polarity Protection: Includes onboard reverse-connection protection (up to 5A) to guard against accidental battery polarity reversal.
• Up to 250W Power Handling: Delivers 72W at 12V input, 144W at 24V input, and up to 240W–250W at 36V–40V input when mounted to an auxiliary heatsink or airflow.
