Introduction: Wide voltage input 5.5-30V, wide voltage output 0.5-30V, both boost and buck. For example, if you adjust the output voltage to 18V, then the input voltage will change between 5.5-30V, and the output will be constant at 18V; For example, if you input 12V, adjust the potentiometer to set any output from 0.5-30V.
High power, high efficiency and better performance than XL6009/LM2577 solution. The external 60V75A high-power MOS is used, and the high-current and high-voltage Schottky diode SS56 is connected in parallel. It is not comparable to the SS34 of the 6009 or 2577 scheme, because according to the buck-boost principle, the withstand voltage of MOS and Schottky is greater than the sum of the input and output voltages.
FeSiAl magnetic ring inductor, high efficiency.
Product parameters:
Input voltage: 5.5 -30V
Output voltage: 0.5-30V
Output current: can work stably at 3A for a long time, and can reach 4A with enhanced heat dissipation
Output power: natural heat dissipation 30W, enhanced heat dissipation 50W
Conversion efficiency: about 88%
Short circuit protection: yes
Working frequency: 180KHZ
Size: L*W*H 56*20*21mm
Weight: 17g
Precautions:
1. This module is a constant voltage type, and is not recommended for battery charging or LED driving where constant current is required
2. Please ensure that the power of the power supply is always greater than the power required by the output load!
3. The module input has no input anti-reverse connection function, please pay attention to the positive and negative directions of the power supply.
4. If the module wants to output at full load, the input voltage should be above 7V. When the input voltage is 5.5V, the output power is about 15W.
5. The module has output short-circuit protection. After the short-circuit protection, the module automatically turns off the output, and the module can be restored by re-powering it. If your power supply has no output current limiting protection, it is recommended to connect a fuse in series at the front of the module input to improve the safety factor.
6. The module has the function of input under-voltage protection, the default is about 5V, after the value is lower than this value, the output will be automatically disconnected, and the module can be restored by powering on again (note that the voltage at the module port, when the input current is relatively large , do not ignore the voltage divider on the input wire).
