Product description: S8V9F3 - step-up / step-down converter - 3.3 V 1.5 A - Pololu 4964
Pololu brand converter with an output voltage of 3.3 V and efficiency of 1.5 A. The supply voltage is from 1.4 V to 16 V. It is used to convert both higher and lower input voltages to a constant output voltage. This is an ideal solution for many applications, especially in battery-powered devices . The S8V9F3 offers efficiency from 80% to 90% , which helps minimize energy loss and extends battery life. In addition, the converter is equipped with protection functions such as protection against overvoltages , overcurrents and excessive heating, which ensures safe and reliable operation of the system. Additionally, it has a soft start function that limits the starting current and gradually increases the output voltage during startup, and an energy saving function that ensures high efficiency even at low output currents.

Pinouts of the S8V9F3 converter.
Pinouts of the S8V9F3 converter
- VOUT - output voltage 3.3 V
- GND - system ground
- VIN - input voltage from 2.7 V to 16 V (after starting the system, the input voltage may drop to at least 1.4 V)
- EN - allows you to control the regulator's operation by setting it to low or high
LC voltage spikes
When applying voltage to electronic circuits, sudden current flows can generate voltage spikes that exceed the input voltage. If these spikes exceed the maximum voltage of the converter, it may damage the converter. When using voltages above 9 V , using long power cables, or using power supplies with high inductance, it is recommended to place an electrolytic capacitor with a capacity of 33 μF or more near the regulator between the VIN and GND pins. This capacitor should have a voltage rating of at least 20 V.
The device processes a wide range of input voltage and sets a constant value of 3.3 V.
Current efficiency of the converter.
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 S8V9F3 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.
