LM2596 Buck Converter DC Voltage Regulator Adjustable Step_Down Power Module 3.0_40V to 1.5_35V Power Supply Step Down Module

Specification: Dimmension: 16.93 x 8.27 x 51.51inches IN+ input positive, IN- output negative OUT+ output positive, OUT- output negative Dimensions: 45 (L) 20 (w) 14 (H) mm (with potentiometer) Input Voltage range: DC 3.2V ~ 36V (Max below 35DCV, input voltage must be higher 1.5V than output voltage, can't boost) Output Voltage range: DC 1.25V ~ 34V (Max below 32DCV) voltage continuous adjustable,high-efficiency maximum output current of 3A Conversion efficiency: 92% (the highest) Working Temperature: - 40 ? to + 85 ? Measured 12V input, 5V output current is 1A load regulation rate of less than1% Warm Tips: 1.this is the step-down module, the input voltage must be higher than the output voltage 2.Pls don't reflect in connect the circuit on input/output, or it might burn off Package included: 4 x DC-DC Voltage Buck Converter
