Detail LM2596 adjustable DC-DC step down module DC Buck - LED INDICATOR
LM2596S DC-DC Step Down Power Module Input Coltage : 3.2V ~ 40V Output Coltage : 1.25V ~ 35V Output Current : 3A (max) Conversion Efficiency : 92% (maximum) Output Ripple : 30mV Switching Frequency : 65KHz Operating Temperature : -45 ' ~ +85 ' Size : 43mmx21mm x14mm (L W H) IN-IN + input Positive Input Negative! Positive output OUT + OUT-output negative
Input voltage range DC 3.2V to 40V (input voltage must be greater than the output voltage to 1.5V or more high. Could not boost)
Output Voltage Range 1.25V to 35V DC voltage continuously adjustable, high efficiency (up to 92%) the maximum output current of 3A, Measured 12V input, 5V output current is 1A load regulation rate of less than 1%
Note This is the step-down module, the input voltage must be higher than the output voltage.Output current is greater than 2.5A (or output power greater than 10W) to work long hours, please add heat sink
