Product description: S8V9F9 - step-up / step-down converter - 9 V 1.5 A - Pololu 4968
A small step-up/step-down voltage converter module offers a stable 9 V output and the ability to supply a maximum current of 1.5 A. The device can be powered in the range from 1.4 V to 16 V. These types of converters are commonly used in projects where voltage adjustment is necessary, for example when using batteries. The efficiency of the regulator ranges from 80% to 90% , and its ability to supply current depends on the input voltage, ranging from 1 A to 1.5 A. The module is equipped with many protections , such as undervoltage lock, output overvoltage protection and protection against too high voltage and current. Additionally, an over-temperature shutdown function prevents overheating damage, and a soft start function controls the starting current and gradually increases the output voltage during startup.
S8V9F9 - step-up / step-down converter - 9 V 1.5 A - Pololu 4968.
The converter has a number of protective measures.Main features of the converter
- Input voltage range: 1.4V to 16V
- Output voltage: 9V with an accuracy of 4%
- Typical maximum continuous output current: 1 A to 1.5 A, depending on input voltage
- Typical efficiency: 80% to 90%, depending on input voltage and load
- Typical quiescent current below 4 mA, which can be reduced from 10 µA to 15 µA per volt per VIN by turning off the board
- Soft-start function that limits the turn-on current and gradually increases the output voltage at start-up
- Protection against excessive current and overheating
- Input voltage lock
- Energy saving function ensuring high efficiency at low currents
- Compact size: 10.2 x 16.5 x 2.6 mm makes it easy to integrate with various types of boards
Pinouts of the S8V9F9 converter
The converter has through-holes spaced 0.1" apart along the edge of the board, which makes it compatible with standard breadboards and solderless perforated boards and connectors that use a 0.1" mesh. You can connect the wires directly to the board or solder them to the included goldpin strip as needed.
- VOUT - output voltage 9 V
- GND - system ground
- VIN - input voltage from 1.4 V to 16 V
- EN - allows you to control the regulator's operation by setting it to low or high
Applications of the converter
The Pololu S8V9F9 converter is an excellent solution for applications that require a stable output voltage based on a wide range of available input voltages. It is ideal for use in battery systems, robotics, portable devices and wherever it is necessary to provide a stable voltage of 9 V from various energy sources.
