300W 10A DC-DC Step Down Buck Converter Input 7-40V to Output 1.2-35V Module

The 300W 10A DC-DC Step Down Buck Converter Module is a high-performance voltage regulator with a wide input voltage range of 5-40V, capable of providing an adjustable output voltage ranging from 1.2V to 35V. Here are the detailed specifications and features of this module:

  Features:  

1. Adjustable output voltage ranging from 1.2V to 35V.
2. High output current capacity of up to 10A.
3. Suitable for battery-operated projects requiring a higher current regulated power supply.
4. Fixed lamp current is 0.1 times of the constant current value, used to identify whether the battery is full when charging.
5. Dedicated reference IC and high-precision sampling resistor for stable constant current (temperature drift is less than 5% at a constant current of 5 degrees from 20 to 60 degrees).
6. Four high-frequency capacitors to reduce output ripple and improve working stability.
7. Double heat sink design for MOS tube and Schottky diode, ensuring good heat dissipation.
