Automatic Step-up and Down Power Supply Modul Voltage Regulator Modul A3GS
Automatic step-up buck power supply module adjustable voltage 0.5-30V power supply buck and boost 4A Wide voltage input 5.5-30V, wide voltage output 0.5-30V, both boost can also buck, such as you adjust the output voltage of 18V, then the input voltage between 5.5-30V casually change, will be constant output 18V; and then you Input 12V, adjust the potentiometer to set 0.5-30V arbitrary output; high power, high efficiency, better performance than XL6009 / LM2577 program. 4A BUCK and BOOST modules (constant voltage version) XL6009 / LM2577 on the market using a single SS34 rectifier, the first pressure value is not enough, according to the principle of starting and lowering the rectifier and switch tube voltage value is greater than the maximum input voltage plus the maximum output voltage.
