Pololu D24V5F5 - Converter step-down 5 V-0,5 A.


In our offer available version with an output voltage of : 1.8 V, 2.5 V, 3.3 V, 5V, 6V, 9V, 12V and 15V.



The module has four output:

  • VIN - input voltage.
  • GND - the ground.
  • VOUT - output voltage.

In the holes, you can solder a popular strap goldpin findings raster is 2.54 mm (included in delivery). The module can be mounted on the contact plate, connect via wires or put in a dedicated circuit Board.


Efficiency and output current

Efficiency is defined as the ratio of output power to input power (Power out)/(Power in). This is a very important parameter for portable energy sources (batteries and accumulators), which has a value of working time on one cycle charging. The dependence of the efficiency on the input voltage given in the diagrams below.



Voltage drop-out

The graph below shows the dependence of the voltage drop-out from the value of the output current. For example, if the consumption of 200 m, the output voltage must be higher than 0.25 V input.



Hazardous voltage pulses

When connecting power to the module, can appear dangerous, eclectic short pulses of high amplitude (so-called pins), which can damage the system. Test company, Pololu, it follows that for voltages above 20 Volts, the pins can have an amplitude in excess of 42 V. to protect against this undesirable phenomenon wlutowanie recommended capacitor value of at least 33 uF / 50 V as close as possible to the power pins of the Converter.
