The Converter is used to supply circuits operating with a voltage of 5 V. the circuit has a wide input voltage range, making it ideal in designs working with batteries. Application S7V7F5 provides stable power throughout the discharge cycle of the battery. In order to increase the reliability module is equipped with short circuit protection and automatic power-off if be exceeded permissible operating temperature.


Our range also has a kit for the manufacture of chargers for smartphones together with instructions for on-line.

Method of application

The module is very simple to use, has three main conclusions:

  • VIN - the input voltage between 2.7 V and 11.8 V. lower module will not turn on, above, may damage the system.
  • GND - the ground.
  • VOUT - output voltage of 5 V.



Valid input voltage range is from 2.7 V to 11.8 V. At lower values the controller will not turn on. A higher voltage may damage the system.


Tense weekend set at 5 Volts, but can range up to 5.2 V, with no or low load.


Connectors respectively signed on the Board. Terminal pitch is 2.54 mm (goldpin connectors). The module can be mounted on the contact plate, to connect with wires or solder in a special printed circuit Board.


Output current

The maximum current that can go through the system depends on the value of the input voltage. The dependence of this graph specify below:


The maximum output current as a function of the input voltage.



This parameter is of particular importance when running on battery power when it is important that the system worked as long as possible on a single charge. The efficiency of the Converter depends on the strength of the current flow and the input voltage (chart below). The average is at the level of 85-95 %, which allows to use almost the maximum energy from the battery.

Jumping voltages (pins)

In electronic circuits, the current run can lead to the emergence of so-called pins, that is, sharp voltage spike to a value above a certain level. If the amplitude of the pin exceeds the permissible value of the controller, it can fail. Therefore, if the system will be powered with voltage not higher than 9 V or the load will have high inductance, we highly recommend you wlutowanie capacitor value of 33uF/25V or higher, as close as possible to the system between VIN and GND.
