XL6009 Adjustable DC-DC Booster Power Supply Module
₦ 2,250Description:-
XL6009 module is a non-isolated step-up boost voltage converter featuring adjustable output voltage, high efficiency. It converts input voltage of 5-32V DC to an output voltage of 4-38V DC.
Features:-
Wide input voltage 3V ~ 32V, optimum operating voltage range is 5 ~ 32V;
Wide Output voltage 5V ~ 35V;
Built-4A efficient MOSFET switches enable efficiency up to 94%; (LM2577 current is 3A)
High switching frequency 400KHz, can use a small-capacity filter capacitors that can achieve very good results, the ripple smaller and smaller. (LM2577 frequency only 50KHz)Test Results:-
Input 3V Output 12V 0.4A 4.8W
Input 5V Output 12V 0.8A 9.6W

Technical Parameters:-
Module Properties: Non-isolated boost (BOOST)
Rectification: Non-Synchronous Rectification
Input Voltage Range: 3V ~ 32V
Output Voltage Range: 5V ~ 35V (Note: If you want to get the max voltage, you should make the input current as least 3A)
Input Current: 4A (max), no-load 18mA (5V input, 8V output, no-load is less than 18mA. Higher the voltage, the greater the load current.)
Conversion efficiency: <94% (greater the pressure, the lower the efficiency)
Switching frequency: 400KHz
Output Ripple: 50mV (the higher the voltage, the greater the current, the greater the ripple)
Load Regulation: ± 0.5%
Voltage Regulation: ± 0.5%
Operating Temperature: -40 ? ~ +85 ?
Dimensions: 43mm * 21mm * 14mm (L * W * H)
When using these modules remember that the output current will be a lot less than the input current, (remember – W = VA). For example, if you have a 10V output at 1A from a 5V input, the input current will be around 3.6A. The real-life maximum amount of power you can get out of these things is around 10W.Output current is greater than 2.5A (or output power greater than 10W) to work long hours, please add heat sink.
