pakai IC LM2596S Tegangan input : 3.2 V - 40 V The output voltage : 1.25 V - 35 Arus Max : 3 A (Max) Conversion efficiency :92% (the highest) The output ripple : < 30 mv Switching frequency : 65 KHZ Working temperature : - 45 ~ + 85 size 43 mm * 21 * 14 mm mm (length * width * height)
Connection port: IN + enter the positive - negative input IN! The positive OUT - output negative OUT + output Range of input voltage: 3.2 V dc to 40 V, the input voltage must be higher than to the output voltage of 1.5 V or more. Can't booster) Range of output voltage: 1.25 V dc to 35 V voltage continuously adjustable, high efficiency (92%) of the maximum output current is 3 a. Measured input 12 v and 5 v 1 a output current at the time of the load regulation is less than 1% Note: this is step-down module, the input voltage must be higher than the output voltage. 2 A output can long time don't need to add heat sink under the output current is greater than 2.5 A (or output power greater than 10 w) work please add heat sink for A long time.
