It is a Car Adapter/Power Supply Module/Charger, Input Voltage: DC 4.5~24V, Output Current: 3A max, Suitable for DIY an adjustable voltage regulated power supply, Industrial equipment Voltage convert, Power Supply Transformers, Car Power Supply etc.

• Input Voltage: DC 4.5~24V
• Output Voltage: Integrated adjustable and fixed output (Adjustable range is 0.8~17V, fixed output are 1.8V, 2.5V, 3.3V, 5V, 9V, 12V that can be chosen on the back side)
• Output Current: 3A max (please enhance cooling work when it is full load); When real tested input 12V and output is 1.5A, no need to add special cooling system.
• Conversion Efficiency: 97.5% (highest) (6.5V to 5V, 0.7A)
• Switch Frequency: 500KHz
• Output Ripple: 20mV(12V to 5V, 3A)  20M width
• Operating Temperature: -40°c ~ +85°c (Industrial class) (The higher the operation temperature is, the smaller the output power is)
• Output Over-voltage Protection: no
• Temperature rising range at full load: 40°c
• Static Current: 0.85mA
• Load Adjustment Rate: ±1%

• Dynamic Response Speed: 5% 200uS
• Output Short-circuit Protection: yes, please don’t keep making it short-circuit.
• Input Reverse Connection Protection: no (If necessary, add a diode to IN+)
• Enable Function Control: yes, low electric level will stop working when high electric level is working. High electric level is 2-5V, low electric level is 0V or so.
• Wiring Method: soldering
• Input Method: soldering
• Output Method: soldering or pins
• Welding Hole Spacing: 2.54mm

• Strong and high quality constructions: imported potentiometer and 3A current chip, high current shielded inductors and MLCC solid capacitance with super long service life.
• High efficiency and super compact size, high frequency and low ripple, stable working performance, wide range of applications, will be a good component for fixing work.
• Input and Output requirements: input voltage range is 4.5-24V, adjustable output voltage range is 0.8-17V, fixed output voltage are 1.8V, 2.5V, 3.3V, 5V, 9V, 12V that can be chosen on the back side; max output current is 3A.
• Integrated enable port defaults the working mode and it will be off when it is at low electric level, which bring a great convenience for users.
• Output integrated adjustable and fixed voltage, you can get fixed output voltage by soldering the pot on the board. If the fixed output voltage is not what you want, you can get them by adjusting potentiometer.
