Description of product: Pololu D24V5F15 Converter step-down - 15 to 0.5 A

The regulator switching DC-DC converts the input voltage in the range of 15.1 V* up to 36 V on the output value of 15.0 V. Allows quiescent current to 0.5 A. The system is characterized by high efficiency at 80 % - 93 %.


Pololu D24V5F15 - przetwornica step-down - 15V 0,5A

Pololu D24V5F15 Converter step-down - 15 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 consumption of 300 m the output voltage must be higher than 0.5 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 Volts. 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.
