Description:
Automatic step-up buck power supply module adjustable voltage 0.5-30V power supply buck and boost
3A/4A BUCK and BOOST modules (constant voltage version)
Wide voltage input 5.5-30V, wide voltage output 0.5-30V, both Step Up voltage can also Step Down voltage, such as you adjust the output voltage of 18V, then the input voltage between 5.5-30V casually change, will be constant output 18V; then For example, you input 12V, adjust the potentiometer settings 0.5-30V arbitrary output.
High power, high efficiency, better performance than XL6009 / LM2577 program. Using external 60V 75A high power MOS, parallel high current high withstand voltage Schottky diode SS56. Not SS34 of 6009 or 2577 program can be compared, because according to the principle of step-up and down, MOS and Schottky's pressure is greater than the sum of the input and output voltage. Iron silico aluminum magnetic ring inductance, high efficiency.
Specification:
Input voltage: 5.5-30V
Output voltage: 0.5-30V
Output current: long-term stability work in the 3A, can reach 4A when strengthen the heat
Output power: natural heat 30W/35W, to strengthen the heat 50W
Conversion efficiency: 88% or so
Short circuit protection: Yes
Operating frequency: 180KHZ
Size: Length * Width * Height 56 * 20 * 21mm
Features:
1. This module is a constant voltage version type, is not recommended for battery charging or LED drive and other occasions which need constant current.
2. Make sure that the power of the power supply is always greater than the power required for the output load!
3. Input of the Module without anti-reverse function, please pay attention to the direction of power supply positive and negative.
4. If you want the module can the maximum power output,Input he voltage above 7V or more. When the input voltage is 5.5V, the output power is about 15W.
5. Module with output short circuit protection.Module automatically shut down the output,after short circuit protection . To re-power the module which can be restored. If your power without output current limit protection, it is recommended to concatenate fuse in the front end of module input, in order to improve safety .
6. The module has input undervoltage protection function, the default is about 5V,it will automatically disconnect the output after below this value, to re-power the module and be restored (note : it is the voltage at the port of the module , when the input current is relatively large , do not ignore the input partial voltage on the wire).
