1).. Model Specification: Automatic Buck-Boost module Module Properties:Non- isolated boost (BOOST) Rectification:Non- Synchronous Rectification Input Range:3.8V - 32V Output Range:1.25V - 35V Input Current:3A ( max ) , no-load 18mA (5V input , 8V output , no-load is less than 18mA. Higher the voltage , the greater the load current . ) Conversion efficiency:Switching frequency:400KHz Output Ripple:50mV ( the higher the voltage , the greater the current , the greater the ripple ) Load Regulation:± 0.5% Voltage Regulation:± 0.5% Operating Temperature:-40 - +85 Dimensions:48mm * 25mm * 14mm ( L * W * H )
Function key: -Short press: input/output display options -.Moderate press: Enter the fine-tuning state .Increase or decrease the offset (the default is 0), when the voltage display inaccurate use .Short according to the regulation, long press or long according to restore -Long press: the state of low power consumption, the digital tube and the lights are out, the normal work of the module. Click the button again to restore. Normal display
Clockwise to adjust output voltage: Clockwise----- increasing voltage Counterclockwise----reduce the voltage
3). Model: boost module Module Properties: Non-isolated boost (BOOST) Rectification: Non-Synchronous Rectification Input Range: 3V ~ 32V Output Range: 5V ~ 35V Input Current: 4A (max), no-load 18mA (5V input, 8V output, no-load is less than 18mA. Higher the voltage, the greater the load current.) Conversion efficiency:
