Model/Name: LM2596S DC-DC step-down module Input voltage: 3.2V~40V Output voltage: 1.25V~35V Output current: 3A (maximum) Conversion efficiency: 92% (maximum) Output ripple: <30mV Switching frequency: 65KHz Working temperature -45℃~ +85℃ Size: 43mm * 21mm * 14mm (length * width * height) ------------------------------------------------------------------------------------- IN+ input positive IN- input negative! OUT+ output positive OUT- output negative Input voltage range: DC 3.2V to 40V (The input voltage must be 1.5V higher than the output voltage. It cannot be boosted) Output voltage range: DC 1.25V to 35V continuously adjustable voltage, high efficiency (maximum 92 hundred), the maximum output current is 3A. Measured 12V input, 5V output current 1A load regulation rate is less than 100 Note: This is a step-down module, and the input voltage must be higher than the output voltage. If the output current is greater than 2.5A (or the output power is greater than 10W), please add a heat sink to work for a time. ------------------------------------------------------------------------------------------------ The default is about 18V, and one turn counterclockwise will reduce it by about 1V (clockwise boost, counterclockwise buck)-------------- Points for attention: When encounter output voltage cannot adjust, always be equal to input voltage when this kind of problem, please first counterclockwise rotate potentiometer 10 circles above, use a module to be able to adjust voltage normally. The default output voltage of the step-down module is about 18V.
