Product details of 12 A Adjustable Step-Down DC-DC Module. Overview: This product is a step-down voltage source, high power (maximum 300 W provided with additional dissipation). This module can be used to obtain voltages of 0.8 V to 28 V, 7 V from 32 V, with a maximum current of 12 A, providing a suitable cooling. This is small in size with a very good efficiency, up to 95%, and very little heat dissipation, as compared with the power control. With this circuit, you can build your own source laboratory with adjustable voltage and current or you can include it in your projects. Moreover, you can control LED power or recharge batteries safely. Specifications: • Input Voltage: 7 V to 32 V • The input voltage must be greater than the minimum 1 V output • Output Current: 0.2 A to 12 A (for maximum current must improve heat dissipation) • Maximum Output Power: 300 W • Efficiency: up to 95% • Operating Frequency: 300 kHz • Ripple: 50 mV (measured at 24 V –> 12 V, 5 A) • Leakage Current: 20 mA (at 24 V ->12 V) • Adjustable output voltage and current • Dimensions: 65 x 47 x 23.5 mm Applications: Adjustable power supply (12A power enough), high-power LED drive, LED display drive, lead-acid battery charging, lithium battery charging, car power supply, car laptop power supply (buck), regulated power supply, low-voltage system power supply, (such as children The toy car uses 12V battery to step down to 6V), 24V to 12V 12A 12V to 5V 12A 24V to 5V 12A 24V to 19V20V, etc., the application range is very wide. 1. The fixed lamp current is 0.1 times the constant current value (used to identify whether the battery is full when charging); 2. A dedicated reference IC and high-precision sampling resistor are used to make the constant current more stable (the temperature drift is less than 5% when the constant current is 5A from 20 degrees to 60 degrees). Especially suitable for LED driver 3. The output current is large, the output current can reach 12A, which meets most needs. 4.4 high-frequency capacitors, effectively reducing output ripple and improving working stability 5. Double heat sink design, independent heat sink for MOS tube Schottky diode, good heat dissipation, no mutual influence 6. Use large-size sendust magnetic ring at any cost to improve work efficiency, and use pure copper double wires to reduce heat generation and increase rate. 7. 3296 multi-turn potentiometer, high precision of voltage and current adjustment, good stability. 8. The special current sampling resistor has high current sampling accuracy, good stability, and low temperature drift. LED . 9. Two-color indicator light, the working status is clear at a glance. Recharge. 10. The voltage and current are all adjustable, and the effect of making an adjustable power supply is good. The 12A current is large and the power is sufficient. Don't delay, buy today.
