Features LCD can display input and output voltage output current output power Input anti reverse protection reverse connection will not burn It can be boosted can be stepped down the output voltage can be adjusted freely from 0 5 30V and the current limit of 0 4A can be adjusted freely The output is protected against backflow and there is no need to add an anti backflow diode when charging the battery The button controls the output ON OFF status and the power on default can be set to ON or OFF Using the buck boost chip as the main controller the external 60V 75A MOS tube is used as the switch tube double 60V 5A SS56 Schottky for rectification 60V withstand voltage value better than the market XL6009 LM2577 immature solution many The device withstand voltage is insufficient the MOS tube and Schottky diode withstand voltage must be greater than the input plus input voltage value The output ripple is small and there is LC filtering With heat sink the module supports the spacer Specifacations Input voltage 5 5 30V when the input voltage is 5V the buck boost can also be realized but the voltage and current measurement is not accurate below 4 7V under voltage protection Output voltage 0 5 30VOutput current can work stably at 3A for a long time and can reach 4A under enhanced heat dissipationOutput power natural heat dissipation 35W enhanced heat dissipation 50WVoltage display resolution 0 05VCurrent display resolution 0 005AConversio
