DCDC Converter DROK Step Down Voltage Regulator Module DC 4.5-40V 36V 24V to 1.25-37V 12V 9V 5V 3V Variable Buck Converter Adjustable Electronic Power Supply Volt Reducer Transformer Stabilizer Board

Parameters: Input voltage: 4.5-40V Output voltage: 1.25-37V(consistently adjustable and recommend you adjust when in empty load) Output current: 2A rated current and 3A Max(please add heatsink) Load adjust ratio: +/-0.5% Voltage adjust ratio: +/-2.5% Transferring efficiency: 92% Max(the higher output voltage, the higher efficiency) ON/OFF frequency: 150KHz Output ripple: 200mV Power consumption when in static state: only about 3A Working temperature: -40 Celsius to 85 Celsius Module feature: buck and non-isolated Rectification method: non-synchronous rectification Adjust method: please use a mini screwdriver to adjust output voltage by adjusting the potentiometer Note: 1.Please add heatsink when the output power is larger than 15W 2.Please make sure the voltage difference between input voltage and output voltage is at least 1.5V to ensure stable output 3.Please note there is no reversed connection protection, so check the polarity of input voltage before power on to avoid burning due to reversed connection. 4.It has over-temperature and short-circuit protection. Package includes: 1pcs LM2596 bare board
