DC DC 9A 300W Step Down Buck Converter 5-40V To 1.2-35V Power Module For Arduino

Product Description
1. Fixed lamp current is 0.1 times of constant current value (used to identify whether the battery is full when charging);
2. A dedicated reference IC and a high-precision sampling resistor are used to make the constant current more stable (the temperature drift is less than 5% at a constant current of 5 degrees from 20 degrees to 60 degrees). Particularly suitable for LED drivers
3. The output current is large, and the maximum output current can reach 10A, which meets most needs.
4. 4 high frequency capacitors to effectively reduce output ripple and improve working stability
5. Double heat sink design, MOS tube Schottky diode independent heat sink, good heat dissipation, mutual influence
6. At the cost, the large-size iron-silicon-aluminum magnetic ring is used to improve the working efficiency, and the pure copper double wire is used to reduce heat and improve efficiency.
7.3296 multi-turn potentiometer, high voltage and current regulation accuracy, good stability.
8. Dedicated current sampling resistor The current sampling precision is high, the stability is good, and the temperature is small. LED is a must.
9. Two-color indicator light, the working status is clear at a glance. Rechargeable.
10. The voltage and current are all adjustable, and the adjustable power supply is good. The 10A current is large and the power is sufficient.

Applications:
1. High-power LED driver.
2. Lithium battery(or lead accumulator) charge.
3. Vehicle-mounted power supply.
4. Low voltage system power supply.
5. 6V, 12V, 14V, 24V battery charge.
6. On-board laptop power supply.
7. regulated power supply.
8.Low voltage power supply system.
