Описание
The Pololu S13V25F12 step-up/step-down converter is an advanced electronic device that effectively converts input voltages ranging from 2.8 V to 22 V into a stabilized output voltage of 12 V. The device has small dimensions and is characterized by efficiency from 85% to 95% . It also offers a number of various protections to ensure a high level of safety and includes an optional EN input that allows the converter to be switched to a low current consumption state.
S13V25F12 - step-up / step-down converter - 12 V 2.5 A - Pololu 4984.
The device processes a wide range of input voltage and establishes a constant value of 12 V.
- 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
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.
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.
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
