Model Number : LM2596 Phase : Single Phase Current Type : DC Usage : module Name : LM2596 DC-DC Buck module Input voltage : 4V ~ 35V The output voltage : 1.23V ~ 30V Output Current : 3A ( Max) Conversion efficiency : 92% ( MAX ) Output ripple : Switching frequency : 150KHz Working temperature : -forty Five~ +85 Size : 43mm * 21mm * 14mm (Long*Width*Hight) Features : 1. the range of input voltage: 3.2 V to 40 V dc (input voltage must be higher than to the output voltage of 1.5 V above. Can't booster) 2. the range of output voltage: 1.25 V dc to 35 V voltage adjustable, high efficiency (92%) largest maximum output current is 3A. Instructions : 1. Power (3-40V), power indicator light, the module is working properly. 2. Adjust the blue potentiometer knob (clockwise rotation generally boost, counter-clockwise rotationTurn down) and reach with a multimeter to monitor the output voltage required voltage. Note : Current work long hours is recommended for use in less than 2.5A, while adding bulkHeat sink (10W output above), because it is the step-down module, in order to ensure stable output Set, please keep the minimum 1.5V differential.
