Mini DC-DC 12-24V To 5V 3A Step Down Power Supply Module Voltage Buck Converter Adjustable 97.5% 1.8V 2.5V 3.3V 5V 9V 12V

Module parameters

• Module Properties: non-isolated step-down module (BUCK) synchronous rectifier.
• Input voltage: DC 4.5-24V(Use to leave a margin, generally about 20V. When the input is 24V, an electrolytic capacitor of more than100uF can be connected in parallel at the input and output to avoid burning the board.)
• Output voltage: integrated adjustable and fixed output, the back can choose a fixed output voltage
• Adjustable range (0.8-17V), fixed voltage (1.8V 2.5V 3.3V 5V 9V 12V)
• Output Current: 3A (Please note that full cooling), the actual test input 12V 1.5A output less heat without special treatment.
• Conversion efficiency: 97.5% (6.5 turn 5V 0.7A)

• Switching Frequency: 500KHz
• Output ripple: 20mV around (12V turn 5V3A) 20M-bandwidth

• Operating temperature: Industrial grade (-40°C to +85°C) (the higher the temperature, the smaller the output power)
• Output Overvoltage Protection: None
• Full load temperature rise: 40°C
• Static current: 0.85mA
• Load regulation: +1%
• Voltage regulation: +0.5%
• Dynamic response speed: 5% 200uS
• Output short circuit protection: Do not short-circuit a long time
• Input reverse polarity protection: None, input reverse polarity protection diode
• Enable control: Yes, high work, low stop working, high level 2-5V, a low level of about OV. The default input with internal pull-up to the positive electrode.
• Connection: Welding
• Input: Welding
• Output: welding/pin
• Welding hole spacing: 2.54 mm

The default output is adjustable.lf you need to fix the output voltage,use a knife to cut the wire in the red circle, then connect the pad with solder at the voltage position you need.
