Product description: Polol D24V10F5 - step-down converter - 5 V, 1 A

The DC-DC pulse controller converts the input voltage from5.1 V*to36 Vinto a5 Voutput value. It allows for current consumption of up to 1 A. The system has a high efficiency of80 % - 93 %.

Versions with an output voltage of3.3 V,5 V,6 V,9 Vand12 Vare available.

Pololu D24V10F5 - step-down converter - 5 V, 1 A.


The module has four outputs:

  • VIN- input voltage from 5.1 V to 36 V - depending on the drop-out voltage.
  • GND- ground potential.
  • VOUT- output voltage.
  • SHDN- low state (below 0.4 V) switches the system into low power mode, where it consumes only 10 uA - 20 uA for each Volt of supply voltage. Pin is pulled to VIN by default through a 100 kΩ resistor. If the low-power mode is not usedSHDNcan be left unconnected.
  • PG- "power good" indicator. The open drain is switched to a low state when the output voltage drops below 80 % or rises above 120 % of the set value (i.e. below 4.5 V for 5 V).

The popular goldpin raster of the outputs is 2.54 mm (the set is included). The module can be plugged into thecontactboard,connected with wiresor placedin a dedicated printed 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 when working with portable energy sources (batteries and accumulators), where the time of operation on one charging cycle counts. The efficiency dependence on the input voltage is shown in the graphs below.

Voltage drop-out

The graph below shows the drop-out voltage dependence on the output current. For example, for a 5 A consumption, the output voltage must be 1 V higher with an input value.

Dangerous voltage pulses

When connecting the power supply to the module, dangerous, short, high amplitude eclectic impulses (so-called pins) may appear, which may permanently damage the system. Polol's tests show that for voltagesabove 20 V, the pinsmay have an amplitudeexceeding 42 V.In order to protect against this undesirable phenomenon it is recommended to solder a capacitor of at least33 uFas close as possible to the pins powering the converter.
