Effective system of the transmitter pulse power, allowing for the consumption of DC 7 A (short-term, up to 16 A). The advantage of the Converter D15V70F5S3 is the ability to select output voltage using jumper. There are two most popular standards: 3.3 V and 5 V.


Method of application

The module has three pins: input , VIN, weight - GND, out - OUT and jumper voltage selection 3v3 SEL.




  • Pin EN (enable) - after podciągnięciu to ground switches the converters in the sleep mode (the system receives then about 150 uA). On the Board is a podciągający resistor between EN and VIN which means that the Converter is enabled by default.
  • Pin VIN (input) - input. Valid range: 4.5 V to 24 V.
  • VOUT Pin (output) - output voltage depends on the setting of jumper 3v3 SEL. If the contacts are closed, the output voltage is 3.3 V, otherwise, 5 V.



The average system efficiency is between 80% to 90%. For example, when the input voltage is 12V output 5V was selected and the average current consumption of the system is about 1.8 A. the Efficiency is 90%. This means that the output power will be determined by the formula:

(Output current) × (output Voltage)= 1.8 A × 5V = 9W

The input power, and is at a level of about 10 V. In 1 to be introduced in the form of heat.


The input current can be calculated by the formula 10 W/12V= 0,83 A.

With these parameters, the loss of the stabilizer of adventure wynosiłyby to 13W.
