Exits
The module has three outputs:
- VIN- input voltage
- GND- mass potential
- VOUT -output voltage
The connectors are properly signed on the board. 2.54 mm leadout Raster - popular connectorsgoldpin, allow the module to be mounted incontact plateorconnectionby means ofcables.
Output voltage selection
The voltage is set using a potentiometer. Turning clockwise increases the voltage.
System efficiencyFig. 1: Selection of output voltage.
The efficiency of the inverter depends on the input voltage and the selected output voltage. On average, it ranges from 80% to 90%. The maximum current that the system can supply is 2 A.

Voltage jumps (pins)
In electronic circuits the starting current may cause the occurrence of so-called pins, i.e. sudden voltage surges to a value above a set level. If the amplitude of the pins exceeds the permissible value of the regulator, it can be destroyed. Therefore, if the system is supplied with voltage above 10V or the load is high inductance, we recommend to solder a capacitor of 33uF/25V or higher as close to the circuit as possible between VIN and GND.
