LM2596 LM2596S DC-DC 3-40V can adjust the voltage of voltage power module 3A

Model/name LM2596S DC-DC Antihypertensive module Input voltage 3.2V~40V Output voltage 1.25V~35V Output current 3A (no more than) Conversion efficiency 92% (no more than) Output ripple On-off level 65KHz Operating temperature -45 ℃ ~ +85 ℃ Size 43mm * 21mm * 14mm (long * wide * high)       Wiring port: IN+ input positive pole IN- input negative pole! OUT+ output positive pole OUT- output negative pole Input voltage range: DC 3.2V to 40V  (The input voltage must be more than 1.5V higher than the output voltage. It cannot be boosted) The output voltage range: DC 1.25V to 35V voltage can be adjusted continuously, and the maximum output current of high efficiency (maximum 92%) is 3A.   (Recommended air load debt) The actual measured load regulation rate at 12V input and 5V output current is less than 1% when the current is 1A. Note: This is a buck module, the input voltage must be higher than the output voltage. Under the output below 2A, you can do not need to add a heat sink output current greater than 2.5A (or output power greater than 10w) for a long time.
