ITEM NAME:DC-DC CV Buck Converter Step-down Power Module 7-32V 12A 2019HOT 0.8-28V Q2 X2T3 Description: the maximum current is 8-9A (Spot: the maximum current is 8-9A, the input voltage is the highest 40V output voltage is about 35V or so) (Due to 12A current chip manufacturers to stop production, replace the chip current from the previous 12A down to 8A current (actual test maximum current in 9A or so), the input voltage from the previous 32V to 40V, the output voltage from the previous 28V to 35V. Power supply for 10 strings of high power LEDs 12A chips are subject to change. QS-2405CCBD-12A power supply module Size: 65 (L) * 47 (W) * 23.5 (H) mm typical application: Adjustable power supply (12A power is large enough), high power LED driver, LED display driver, lead battery charging, lithium battery charging, car power, car notebook power supply (buck), power supply, low voltage system power supply (such as children Toy car with 12V battery buck to 6V), 24V to 12V 12A \\ 12V to 5V 12A \\ 24V to 5V 12A \\ 24V to 19V20V and so on, the application range is very wide. 1. Fixed turn lamp current is 0.1 times the constant current value (used when charging to identify whether the battery is full); 2. Using a dedicated reference IC, and high-precision sampling resistor, so that constant current more stable, (20 degrees to 60 degrees constant current 5A when the temperature drift less than 5%). Especially for LED driver 3. Output current, the maximum output current can reach 12A, to meet most of the needs. 4.4 high-frequency capacitors, effectively reduce the output ripple, improve work stability 5. Double heat sink design, MOS tube Schottky diode independent heat sink, heat is good, do not affect each other 6. At the cost of large-size iron-silicon magnetic ring, improve work efficiency, and with pure copper and Rao, reduce heat, improve efficiency. 7.3296 multi-turn potentiometer, voltage and current regulation of high precision, good stability. 8. Special current sampli.Using a dedicated reference IC, and high-precision sampling resistor, so that constant current more stable, (20 degrees to 60 degrees constant current 5A when the temperature drift less than 5%). Especially for LED driver.
