DC-DC Step-Down Power Module USING LM2596 1.25V-35V

This is a DC/DC step-down voltage regulator that converts input voltage between3.2V and 40V into a smaller voltage between 1.25V and 35V, capable of driving a3A load with excellent line and load regulation.In some projects, you might need different voltages (3-35V) for your devices.Without this kind of DC power source, you'll find it time-consuming to buy a newone. The delay of a project can be so annoying, but no worries! This module canspeed up prototyping, because you can get the voltage you need (such as 3.3V, 5Vand 9V) as easy as that.Input must be >1.5V higher than output.Features:- Wide Output Voltage Range- Ensured 3A Output Load Current- Input Voltage Range Up to 40V- Excellent Line and Load Regulation- Low Power Standby Mode, Typically 80uA- High Efficiency Up to 92%- Precise potentiometer for voltage adjustment- Thermal Shutdown and Current Limit ProtectionSpecifications:- Input Voltage: 3.2V - 40VDC- Output Voltage: 1.25V - 35VDC- Max.
