300W 4A DC-DC Buck Converter Step Down Module Constant Current LED Driver Module

The 300W 4A DC-DC Buck Converter Step Down Module Constant Current LED Driver Module offers adjustable output voltage ranging from 12V to 36V, catering to various applications. With a wide current output range of up to 4A, this module provides ample flexibility for different power requirements. Additionally, when equipped with a heat sink and suitable cooling mechanisms such as a cooling fan, it can effectively handle continuous operation even in high-power applications.

Crafted using a specialized benchmark IC and high-precision current sensing resistor, this module ensures stable constant current performance. With minimal temperature drift (less than 1%) within the temperature range of 20°C to 100°C, it is particularly well-suited for LED driver applications. While the module supports output currents of up to 4A, it is recommended to operate it continuously at up to 3A with the addition of a cooling fan for optimal performance and longevity.

Applications:

1. High-power LED driver.
2. Charging lithium batteries or lead accumulators.
3. Power supply for vehicles.
4. Power supply for low voltage systems.
5. Charging batteries with voltages of 6V, 12V, 14V, and 24V.
6. On-board power supply for laptops.
7. Regulated power supply.
8. Low voltage power supply systems.

Note: If the module temperature exceeds 65ºC, please add a cooling fan (It be used at room temperature without a fan)
