Product description: S8V9F7 - step-up / step-down converter - 7.5 V 1.5 A - Pololu 4967
The S8V9F7 converter is an advanced step-up/step-down regulator that allows you to adjust the input voltage from 1.4 V to 16 V , adapting it to the desired output voltage of 7.5 V. Thanks to this feature, it can be used in a variety of applications, especially those powered by different sources such as batteries. It is characterized by high efficiency, typically between 80% and 90% , which guarantees stable and effective energy supply with minimal losses and limited heat generation. The regulator is capable of continuously delivering an output current of 1 A to 1.5 A as the input voltage approaches the output voltage. In addition, it has a number of protection functions , such as input voltage lock, protection against current overload and overheating, which ensures reliability and safe operation. Additionally, functions such as soft-start limit the turn-on current, protecting components from damage, and the sleep function allows you to save energy in idle mode.
S8V9F7 - step-up / step-down converter - 7.5 V 1.5 A - Pololu 4967.
The converter is suitable for applications with unstabilized voltage.
Main features of the converter
- Input voltage range: 1.4V to 16V
- Output voltage: 7.5 V 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 S8V9F7 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 7.5 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

Efficiency of the converter system
Efficiency is defined as the ratio of output power to input power (Power out) / (Power in). It is one of the most important parameters of the converter, especially when working with portable energy sources. The S8V9F7 delivers typical efficiencies of 80% to 90% , depending on input voltage and load. Thanks to this, you can be sure that the converter operates with the highest possible efficiency, which translates into longer battery life or less heat generation in the system.
