Applications of the converter
The Pololu S13V25F6 converter is a universal device used in various electronic systems. It is particularly useful in projects requiring a consistent voltage source despite varying input conditions. Due to its ability to convert both higher and lower input voltages, it is often used in battery-powered devices due to the voltage fluctuations present.
The converter is suitable for applications with unstabilized voltage. 
Elements included in the set.
Security available
The device is equipped with reverse voltage protection up to 20 V , which prevents damage caused by incorrect connection. It also has an overheat protection function that automatically turns off the inverter at high temperatures and includes overload protection that protects against excessive current. Built-in protections guarantee a high level of safety and reliability of the converter.
Pinouts of the S13V25F6 converter
The controller has two sets of through holes: five smaller holes placed at 0.1" intervals along the edge of the board (for compatibility with standard breadboards and connectors using a 0.1" spacing between pins) and four larger holes intended for screw terminals with spacing 3.5mm.
- VOUT - output voltage 6 V
- GND - system ground
- VIN - input voltage from 2.8 V to 22 V
- EN - allows you to control the regulator's operation by setting it to low or high
