Description： MS + -> Positive; IN ---> Negative; OUT + -> Positive; OUT ---> Negative Input Voltage: DC 3-35 V(40V MAX) Output Voltage: DC 5-40V ( 45V MAX Adjustable) Input Current: 5A (MAX) Conversion efficiency: 94% (MAX) Output ripple: 100mv (MAX) Switching Frequency: 220 kHZ Working Temperature: Industrial (-40 ° C to + 85 ° C) Voltage regulation: ± 0.5% Load regulation: ± 0.5% Instructions: Input and Output must be connected correctly Conventional Constant Voltage Output BOOST Fully Integrated Solutions, Integrated MOSFET, Fewer External Components, Smaller Cos System Built-in over temperature protection, full set overcurrent protection circuit reliability, high reliability TO263-5L standard package, suitable for 30W boost inside applications. Power (3-35 V), power indicator light, module is working properly. Adjust the blue knob of the potentiometer (counterclockwise general impulse, buck clockwise rotation) and with a multimeter to monitor the output voltage reaches the required voltage NOTE: Long hours working current is recommended for use at less than 2.5 M, while adding heatsink mass (10 W output above); Because it is boosting the module, in order to ensure stable output, please keep the minimum differential 1.5 V. Package： 3 * XL6019 5A Current DC to DC Adjustable Boost Power Supply Board Module
