Automatic Buck Boost Module Power Supply Module Voltage Regulator Adjustable Voltage
Features:
- Wide voltage input 5.5-30V, wide voltage output 0.5-30V. It can boost and step down. For example, if you adjust output voltage to 18V, then any change between 5.5-30V input voltage will always output 18V constant. Input 12V, adjust potentiometer to set any output of 0.5-30V.
- High power, high efficiency and better performance than XL6009 / LM2577 solution. Uses external 60V75A high-power MOS in parallel with a high-current, high-withstand voltage diode SS56. It is better than SS34 of 6009 or 2577 solution, because according to buck-boost principle, the withstand voltage of MOS and SS56 is greater than the sum of input plus output voltage.
- FeSiAl magnetic ring inductor, high efficiency.
Specifications:
- Input voltage: 5.5-30V
- Output voltage: 0.5-30V
- Output current: can work stably at 3A for a long time. Can reach 4A under enhanced heat dissipation
- Output power: Natural cooling 30W, enhanced cooling 50W
- Conversion efficiency: about 88%
- Short-circuit protection: Yes
- Working frequency: 180KHZ
- Size: 56 * 20 * 21mm (L*W*H)
- Weight: 17g
Precautions:
- This module is a constant voltage type. It is not recommended for applications where constant current is required, such as LED driving.
- Please ensure that the power of power supply is always greater than the power required by output load.
- Module input has no input anti-reverse connection function. Please pay attention to the positive and negative directions of power supply.
- If the module wants to output at full load, input voltage should be more than 7V. When input voltage is 5.5V, output power is about 15W.
- Module with output short-circuit protection. When short-circuit protection works, the module will automatically turn off output, and it can be restored by powering on the module again. If your power supply does not have output current limit protection, it is recommended to connect a fuse in series with the front end of the module input to improve safety factor.
- The module has input under-voltage protection function, the default is about 5V. Below this value, output is automatically disconnected. Power on the module to restore it (Note: it is the voltage of the module port. When input current is relatively large, do not ignore the divided voltage on input wire).
Package Included:
- 1 x Buck Boost Power Supply Module
