This is a LTC3780 DC-DC Buck Boost Converter which is very useful in building adjustable power voltage for your projects.
This product is a DC-DC step down module with an efficiency of up to 94%. With it, you can lower the voltage of 8 V to 55 V up to a voltage of 1 V to 36 V at a maximum current of 15 A up to a power of 100 W to 200 W.
This product is a downward voltage source that can help you build your own adjustable source or to power a wide range of projects running at power up to 200W. The topology of operation is optimized for high power, this being a synchronous buck type.
XL4015 with Adjustable Current and Voltage DC-DC Step Down Power Supply with Display (5 A)
This LM2596 step-down voltage regulator is useful for obtaining a voltage lower than the input,with very high efficiency of up to 98%.
The D36V6x family of buck (step-down) voltage regulators generates lower output voltages from input voltages as high as 50 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters), which makes them much more efficient than linear voltage regulators. NO Reverse voltage protection!
This compact (0.4″ × 0.5″) switching step-down (or buck) voltage regulator takes input voltages between 4 V and 50 V and efficiently reduces them to a lower, user-adjustable voltage set by an on-board trimmer potentiometer. It has an output voltage range of 2.5 V to 7.5 V and a maximum output current of 600 mA. NO Reverse voltage protection!
