Description

This DC-DC 3V-35VPSU Buck Converter adjustable step-down power Supply module

This LM2596 DC-DC buck converter/ step-down power module with the high-precision potentiometer is capable of driving a load up to 3A with high efficiency.

When the output current is greater than 2.5A, please add a heat sink.

Since DC-DC converter is a switch-mode power supply, its efficiency is significantly higher in comparison with popular three-terminal linear regulators.

The DC-DC operates at a switching frequency of 152 kHz allowing smaller sized filter components than what would be needed with lower frequency switching regulators.

Product description

DC-DC Buck converter
Input voltage: 4V ~ 35V
The output voltage: 1.23V ~ 30V
Output Current: 3A (Max)
Conversion efficiency: 92 %( MAX)
Output ripple: <30mV

1 X DC-DC Step-Down Power Supply

Please Note:
These modules are usually supplied adjusted to maximum output voltage please adjust the output prior to connecting to your project.

When making adjustment please keep in mind you will need quite a lot of rotation of the potentiometer to produce the required output.

If the output voltage appears to be stuck at just under the input voltage, keep rotating the adjustment potentiometer clockwise/ anticlockwise until desired output is reached.
