10x/20x LM2596 DC Step Down Voltage Converter Module Regulator LM2596S Details: LM2596S DC-DC buck converter with good technology and exquisite workmanship. Ideal for replacing the old DC-DC buck module. Made of high quality material ensures long service life. Material: PCB + electronic components Input voltage: 3.2V ~ 50V Output voltage: 1.25V ~ 35V Output current: 3A (maximum) Conversion efficiency: Max. 92% Output ripple: <30 mV Frequency: 65 kHz Operating temperature: -45°C to +85°C Size: 44mm * 21mm * 12mm (L*W*H) IN +: Input positive IN -: negative input OUT +: positive output OUT-: negative output Input voltage range: DC 3.2 V to 50 V (the input voltage must be more than 1.5 V higher than the output voltage). Output voltage range: DC 1.25V to 35V voltage continuously adjustable, max. output current of 3A.   Notes: This is a step-down module, the input voltage must be higher than the output voltage. If the output current is greater than 2.5A (or output power greater than 10W), you should add the heat sink.   Scope of delivery: 10*Backward module
