Botland is an official distributor of Pololu electronics and robotics parts. Countless robots hold at least one component of this brand in their build. Our team guarantees that all Pololu products presented here are original.
The device processes a wide range of input voltage and establishes a constant value of 12 V.
Main features of the converter
- Efficiently converts input voltages from 2.8V to 22V to stable 12V
- It offers typical efficiency of 85% to 95% depending on input voltage and load
- It allows operation with a maximum continuous output current from 0.5 A to 3 A
- It is characterized by an quiescent current ranging from 10 mA to 35 mA
- Protects against reverse voltage and overload
- Provides a soft-start function that limits the starting current
- Enables entry into a low power state with an idle current of 2 µA to 10 µA per volt
- It has undervoltage and overvoltage protection at the output
- It is characterized by compact dimensions, ideal for applications with limited space
- It ensures stable operation at a constant switching frequency of approximately 500 kHz
Applications of the converter
The S13V25F12 converter is designed to produce a stable 12V voltage from a wide range of input voltages, making it ideal for battery- powered applications where the supply voltage may fluctuate significantly during operation. The small size of the product also allows it to be used in projects that are space-limited, e.g. portable devices.
The converter is suitable for applications with unstabilized voltage.
Elements included in the set.
Security available
The converter has a number of protections, such as reverse voltage protection up to 20 V , which protects the device against damage caused by reverse battery connection. It also has overload protection , preventing damage to the device by too high current. Additionally, it protects against overheating using built-in thermal protection and has a soft-start function that prevents sudden voltage spikes when switching on.
Pinouts of the S13V25F12 converter
The controller has two sets of through holes: five smaller holes arranged 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 12 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
