keertan kalp 4 Piece LM2596 DC to DC Buck Converter 3.0-40V to 1.5-35V Power Supply Step Down Module Electronic Components Electronic Hobby Kit Double-Sided PCB

This is high performance DC to DC Step Down Adjustable Power Supply Module. Based on Newly developed LM2596S Wide range Switching Regulator IN + input positive-IN-input negative! The OUT + output the positive OUT-output negative Input voltage range: DC 3.2V to 40V (input voltage must be higher than the output voltage above 1.5V. Could not boost) Output voltage range: DC voltage from 1.25V to 35V continuously adjustable, high efficiency (92%) of the maximum output current of 3A. Conversion efficiency: 92% (the highest), Output ripple: <30mV, Switching frequency: 65KHz, Operating Temperature: -45 to +85, Size: 43mm * 21mm * 14mm (L * W * H) Note: This is a step-down module, the input voltage must higher than the output voltage.
