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
