Features: Input voltage: 3V-32V , Output voltage: 5V-35 V , Input current: 4A (max); High reliability, strong vibrationResistance, good electromechanical performance. Built- 4A efficient MOSFET switches enable efficiency up to 94%; (LM2577 current is 3A); High switching frequency of 400KHz, the ripple is smaller and smaller . (LM2577 frequency only 50KHz); Non- isolated boost (BOOST); Specifications: Material:ABS Size:Approx.4.3x2.1cm/1.69x0.83in Model Specification:DSN6000AUD Automatic for Buck module Module Properties:Non- isolated boost (BOOST) Input Range:3V ~ 32V Output Range:5V ~ 35 V Input Current:4A ( max ) , no-load 18mA (5V input , 8V output , no-load is less than 18mA. Higher the voltage , greater the load current . ) Conversion efficiency:< 94% ( greater the pressure , the lower the efficiency ) Switching frequency:400KHz Output Ripple:50mV ( the higher the voltage ,greater the current , greater the ripple ) Load Regulation: 0.5% Voltage Regulation: 0.5% Operating Temperature:-40 ~ +85 Note: Please allow 1-2cm errors due to manual measurement,pls make sure that you do not mind before you order.
