300W 20A DC-DC step-down converter step-down module constant current LED drive power step-down module electrolytic capacitor

With a wide input voltage range of 6-40V, the buck converter can precisely regulate the output voltage and current.

Up to 96% efficiency (measured at 20 A, converting 24 V to 12 V)

Adopt 75V/80A current dual MOS tube design.

The input and output adopt high-frequency low-resistance electrolytic capacitors, and the output is stable.

High current 30A screw terminal

The step-down module has 2 heat sinks for enhanced heat dissipation.

When the input and output voltage is high, please reduce the power and current.

Specification
Input voltage	6 V to 40 V DC (10 V to 40 V recommended)
The output voltage	1.2V to 36V DC
Output current	20 A (maximum), 15 A (recommended)
efficiency	95% (24V to 12V, 20A)
output ripple	≤50mV
Wiring	terminal
Short circuit protection	self recovery
size	60 x 53 x 27 mm / 2.36 x 2.08 x 1.06 inches

VO+: output positive
VO-: output negative
+IN: input positive
-IN: input negative
CV: output voltage adjustment
CC: output current regulation
EN: enable, low level closes the output; pause, high voltage is active
When the input and output share the same ground, no-load CV output constant voltage, CC output constant current

enter:DC 6-40V, recommend 10-40V
The output voltage:1.2-36V adjustable maximum 300W

Output current:20A max, 15A rated
Conversion efficiency:Maximum 96%
75V, 80A high current dual MOS tube

Frequency: 150KHZ

Output ripple: about 50mV, measured at 24V input
Dual 25mm radiators
High-frequency low-impedance electrolytic input, ultra-low ripple stable output

Working temperature: industrial grade (-30°C to +75°C) (environment temperature exceeds 40°C, reduce power consumption, or enhance heat dissipation)

Some applications:
1. DIY a car power supply with adjustable output, connect to 24V input, the output can be 5-12V (adjustable at will), but the output voltage cannot be higher than the input voltage.
2. Car laptop power supply: connect to 24V power supply, adjust the output voltage according to the needs of the laptop.
