MT3608 Step-up Adjustable DC-DC Converter Power Boost Module 2A 28V

Input Voltage: DC 2V-24V
Output Voltage: DC >5V-28V
Maximum Output Current: 2A
Maximum Coversion Efficiency: 95%
Maximum Operating Temperature: -45C to ~ +85C
Switching Frequency: 1.2MHz
Output Ripple: Less than 100mV

Note that the maximum input voltage should not be greater than the desired output
voltage (as this is a step-up converter not a step down converter).
To adjust the output turn the potentiometer.
