Features: Input Voltage Range: for DC 3.2V to 46V (The input voltage must be 1.5V higher than the output voltage; Output Voltage Range: for DC 1.25V to 35 V continuously adjustable voltage, Maximum output current is 3A. High Efficiency: Output with high power conversion efficiency up to 92%. Measured 12V input, 5V output current, 1A load regulation rate is less than 1%. Requires Attention:It is recommended to use the current within 2.5A for long-term work, and add the scatteredHot Plate (output above 10W); Because it is a step-down module, in order to ensure stable output, please keep a small 1.5Vdifferential pressure; Specifications: Material:ABS Size:Approx.4.4x2.1cm/1.73x0.83in Input Voltage: 3.2V-46V Output Voltage: 1.25V-35 V Output Current: 3A (maximum) Conversion Efficiency: 92% (maximum) Switching Frequency: 65KHz Output Ripple: 30mV (maximum) Working Temperature: -40 to +85 Note: Please allow 1-2cm errors due to manual measurement,pls make sure that you do not mind before you order.
