Model / Name: LM2596S DC-DC step-down module
Input voltage: 3.2V ~ 40V
Output voltage: 1.25V ~ 35V
Output current: 3A (max)
Conversion efficiency: 92% (highest)
Output ripple: &amp;amp;amp;amp;amp;lt;30mV
Switching frequency: 65KHz
Working temperature: -45 ℃ ~ +85 ℃
Size: 43mm * 21mm * 14mm (L * W * H)
IN + input positive IN input negative
OUT + output positive output - output is negative
Input voltage range: DC 3.2V to 46V (input voltage must be higher than 1.5V output voltage, can not be improved)
Output voltage range: DC 1.25V to 35V voltage continuously adjustable, high efficiency (maximum 92%) Maximum output current 3A.
Measuring 12V input, 5V output current 1A when the load regulation rate is less than 1%
Note: This is a buck module and the input voltage must be higher than the output voltage.
Output 2A can be used for a long time, no additional heat sink output current greater than 2.5A (or output power greater than 10W) long time work Please add the radiator.
